• Satellite Z830: Sometimes slow WLan

  Hello!

  I have the problem that my wifi is sometimes very slow.
  It takes 5 minutes to google something.

  Home everything works fine but to (for example) in my college, I compared my wifi with laptops similar speed and they were more than two times faster than mine.

  The bitrate is allgedly to 180 Mbps.

  I use win7 and the driver is real.

  Can someone help me please?

  Thank you!

  > At home, everything works well

  Does this mean that your noticed slow Wifi using the laptop connected to the other wireless LANs and only?

  In my view, this would mean that it is not a card for laptop or wlan problem but the connection/configuration problem.

  Have you noticed the slow Wifi performance using Notepad in battery mode or with an adapter connected?

• B450 USB SPEED SLOW OR IRREGULAR - SOMETIMES SLOW, SOMETIMES FAST?

  Have "Lenovo B450" for about 12 months.  Recently connect 2 drives 2 external t via USB.

  When I transfer files between them, using a synchronization program or other programs - transfer speed is very erratic.  Sometimes runs at 18 + MB per second, then the next transfer (hasn't stopped program) will quickly slow down less than 2 Mbps?  Performance is random?

  I am running XP SP3 Professional.

  The same configuration (and OS) with my desktop PC is constantly fast USB (18 MB/s) transfers between disks?

  Latest lenovo drivers installed.  It seems to be a BIOS problem - please test this on your B450 - Lenovo, please test.

  All solutions?

  I tried all the solutions for slow usb noticed on the web.

  Thank you

  Ray

  SOLVED!  or rather a workaround solution was suggested by LENOVO TECH SUPPORT - a brilliant idea - run in safe MODE, make the file transfers according to normal - I found that speed was always faster to about 25 MB/s using the same synchronization program.

  It seems that some process running in normal mode interferes with USB file transfer speeds.  Could be antivirus, checking files on the fly or something else - weird * beep * huh - Anyhoo, I'll do the transfer of large files in safe mode in the future.  Thanks Lenovo support!

  see you soon,

• Application is sometimes slow

  Hi all

  Told me to check the performance of a FUND of AIX with 10.1.0.2.0

  The customer says they run a certain ratio to 10:00 and all users are simply unable to use their applications as soon as they are dead slow, as this process / job sometimes takes 2-3 hours, which slows down their business process. The same report when generated at the party will take about 30-45 minutes.

  I advise to change the "timing" because users max connection at 10:00 & use the delay, so they have generated the report at 6:30 for example. at the time where few users would come, it took almost 1.45 minutes too.

  I'm confused as to where is the problem, I had generated AWR report & know 2 posts using the time max DB runtime (SQL ORDERED BY ELAPSED i.e.; 51.5% and 19.2% of the time of database) by 1 is a work which is the report (executed several queries nested & it is run ONLY ONCE in a day) and the other is also a work (I got a table of AWR report name which I checked with developers and got to know this dose of table in particular are not not a hint of one and is performed about 12700 times in 1 day).

  I'm not able to get the entire query of the two jobs of AWR report... no idea where I'll be able to find the complete query so that I can get the execution plan for the same...

  I have informed the customer of the State, I want to know what more I need to watch / am I missing something important?

  If I'm not clear, please let me know.

  Thank you

  Florent

  GV,

  Yes, we brought the application server, yet I could find ONLY SYS using the table, so kill this process & created index.

  had tried to create indexes online too... but received the "resource busy" error this is the reason why chose above steps...

  Yes had index created by logging in as a user, not as a sys such that it was created by the developer confirms once again.

• Do a right click in the Project Explorer is sometimes slow

  I have a big project of the AF with a lot of classes and libraries. I only really use these two (lvclass and lvlib) to structure and organize the project. Right click on VI sometimes takes a terribly long time to load, say up to 10 seconds, depending on the library/class. It appears to be vaguely related to how many things the owners have libraries/classes. What exactly is causing this loading time? Any ideas how I could get rid of this significant disadvantage?

  Here is more information and a few thoughts:

  • Windows 8.1
  • LabVIEW 2015 / 32 bit (I can't say for sure, but I think that I had no such problem on earlier versions 2014 and 2013)
  • Mass of compilation of all of the project (taken as 2 hours) had no effect

  Thanks for all the ideas and resources. I'm very, very happy to announce that this particular fix https://decibel.ni.com/content/docs/DOC-44159 (fix for the issue of AF project provider performance) made my problem disappear. Time has been reduced from ~ 7 sec less than a half second. Wonderful! That, to me, proves false the idea that the mere fact of having hundreds of classes or a large AF would make your current IDE experience terrible.

• Aspire T3 - 600 is sometimes slow to connect to Web sites when you first turn on the PC.

• Vista sometimes slow transfer speed nas

  I tried
  http://social.answers.Microsoft.com/forums/en-us/vistanetworking/thread/c5fe4e3f-6b55-421A-8C83-12e459047709
  and it did not work for me.
   
  I have a desktop computer, laptop computer and nas with the shared windows resources box.  To the nas transfer speeds are what is to be expected and more wireless on the laptop and can support about 2.6 MB/s on a wifi 54 G.  The network is a Netgear router to modem wireless CVG824G with wifi 54G and 100 Mbps cable with cable ports.  The office and the nas are connected to the router directly with cat 5 cables and NICs gigabit in them.
  The office is another story.  When plugged in it will copy files to and from the office to the nas to about 8 MB/s, which is around what I expected a 100 Mbps connection, but after it has copied 1 file it slows down to about 500 ~ 600 KB/s until you restart the nas or the office.
  Have a wired 100Mbps connection with transfer significantly more slow speed that a Wifi 54 G Terminal is very annoying.  Desktop or laptops have vista sp2.  The laptop is 32-bit vs 64-bit office.
  I tried various things on the desktop for this problem, including the execution of the command netsh interface tcp set global autotuninglevel = disabled with elevated privileges, different mtu sizes. also the following as well
  netsh interface tcp set global rss = off
  SC config lanmanworkstation depend = bowser/mrxsmb10/ins
  sc config mrxsmb20 start = off
  I think to format and re - install will be necessary.

  Well, I have solved my problem.

  For what follows, socket samba on my nas options have been set

  socket options = SO_KEEPALIVE SO_REUSEADDR SO_BROADCAST SO_SNDBUF = 8192 SO_RCVBUF = 8192

  I decided to leave as a default installation of windows I could without formatting.  To reactivate the smb2 I had turned off before, that vista uses by default and descends to smb1 when necessary, I ran

  SC config lanmanworkstation depend = bowser/mrxsmb10/mrxsmb20/ins

  sc config mrxsmb20 = auto start

  then using TCPOptimizer http://www.speedguide.net/downloads.php with run as administrator to enable elevated privileges, just in case, I put the windows default setting and apply, then restarted
  then with a few tips on how to find my optimal MTU size with ping, I discovered that something along the road could only manage a MTU of 1472.  See somewhere like http://www.dslreports.com/faq/5793 for a howto on this.  And before rebooting, I have disabled auto-tuning then in a window of commands with elevation of privilege, I ran the commands
  netsh interface tcp set global autotuninglevel = disabled

  netsh interface ipv4 set subinterface "Local network connection" mtu = 1472 store = persistent
  then when the computer reboots, he went to max bandwidth.

• sometimes slow acquisition

  Hello

  I developed a labview application, an infinite loop which performs a reading data via Ethernet, place the contents in a specific format and saves it to an oracle DB.

  This loop time varies between 90 ms and 300 ms.

  The strange thing that happens every 30 seconds or so, it's time for this loop is equal to 6 s 9 s and quickly return to the normal rate.

  I was wondering how do you know the reason?
  I disabled the firewall, antivirus, but nothing!

  I even changed the architecture of the Ethernet LAN, with only one cable between the NOR controller Ethernet and my PC, but it doesn't change anything.

  So... How can I find what is happening and conclude the problem please? I have my doubts about the BD (may be occupied by calculations) or Windows Server 2008 service that fires every 30 seconds maybe?

  If anyone can guide me

  Thank you in advance,

  Blue_Strike,

  This looks like a perfect situation for a producer/consumer architecture. The loop of the producer runs at the speed of ~ 90 ms and acquires data from the Ethernet connection. It places the data in a queue.  The consumer loop reads the queue and writes the data in the DB. This loop can run more slowly than the producer without loss of data (so that queue is busy not).  For this success, you need to write multiple DB data sets at the same time so that the loop of consumer can 'catch up' after that the DB was napping.

  Inifintie loops are generally not a good idea. Include a stop button or certain criteria based on data that cause blocking the program.  When a stop command occurs, close the Ethernet connection, write a data accumulated in the DB, close the DB connection, and then stop the program.  If you stop the program using the button abandon, you can do any of the normal shutdown process.

• Since the update to 6,18 windows is slow and unresponsive

  Hello. Since I updated to 6.18 last my Win8.1 (once a day) was sometimes slow and unresponsive, even if the Task Manager indicates that nothing is happening. It takes the Task Manager, 8 seconds to appear. Here, I see that Skype does not respond and when I kill it then system responds once more.

  When I restart Skype I 1/5 chance of having the problem again, so I reboot several times to make it work. When there will be a version 6.18 fixed?

  I can't downgrade because of the stupid idea of "autoupdate" - I can not connect to any previous version, for example, 6.16, even though I have disabled AutoUpdate updates. Who invented this stupid idea of "you cannot log in to the version you want to use?

  It seems I have a solution!

  I found somewhere here on the forums a Council disable smilies in messages to increase performance. And indeed 3 days my Skype does not block or slow down the computer, even though I've updated to the latest version of Skype.

  Finally I have the solution!

• Lag and slow on the new iMac

  I bought an iMac nine retina 5K on a month and half ago and it's already in trouble with the slowness and delay, mostly online. Video and audio, struggle streamer and freezes often after a minute or two, sites are sometimes slow in general, Facebook stops after I scroll down a little ways, and my mouse a significant loading trolling questions (have tried different mouse - same problem). It happens in Safari and Chrome. I want to emphasize that these problems do not occur on my laptop, so I know that is not the internet connection.

  I have very little on this computer and virtually no programs. No games. The only program that I keep running is CC of Photoshop that I use frequently throughout the day, but not should not be the cause of these problems. All the research I've done so far has not helped.

• Slow Internet but network shares are ok

  First of all, here is my configuration:

  Dell Inspiron 15R (5520) Windows 7 64 bit

  ASUS RT-AC68U

  PSI rated speed: 30Mbps

  All the firmware and drivers are up to date and windows updates are enabled.

  I recently bought a new dual band router and have completed the introduction.

  When I try to connect my laptop to this new router via wifi or ethernet, my internet speed is less than 5 Mbps.

  Shared folder from my laptop to the network is very good and the speed is good too.

  iOS and Android devices to the new road via wifi gets 30Mbps full internet speed.

  When I connect the laptop to the old router (not), my laptop is able to get internet 30Mbps speed.

  Is there something I can do to improve the speed of the internet to my laptop computer connected to the router dual-band new?

  Hello

  I understand that concern you. Let me help you with the issue.

  There could be various factors at the origin of the problem as a firewall router, firmware obsolete, obsolete network drivers, bandwidth, etc.

  Are you experiencing the issue when bypass you the router?

  Some instructions that you can follow as indicated below.

  1. Obstruct free paths between your router and receive computers. Physical obstructions more between your router and computer, the lowest, the wireless signal is likely to be. Place the router in a central location with clear lines of visibility on your computer will help boost the signal.
  2. Use a wireless Repeater. Sometimes, it is not possible to move a router and the computer to create direct sight lines, or a computer may be too far from the router to get a strong signal. A wireless Repeater takes in a wireless signal and sends it with increased resistance to increase the signal. Using a Repeater wireless between your router and your computer sends a signal around obstacles and can improve performance.
  3. Reduce signal interference. Like radios, when two wireless networks are in the same area, they can interfere with each other. If you know that another router wireless is close to you, you can move the router to another area or ask the owner of the other router to move sound.
  4. Reduce the use of the network. Sometimes slow Internet use on a wireless network is not the fault of the network, but that too many users are connected to the network. Disconnect other computers connected to the free network bandwidth, and increase the speed. It is also important to block free riders to connect to your network and slowing of setting up your router password protection. Check the user manual of your router on how to set up a password.

  I suggest you to first change the string in the configuration of the router page and check if the problem persists. If many people in your building using the same channel, then you might notice a slowdown in your Internet speed. Switching to one of these channels will reduce interference and possibly increase your speed.

  If the problem persists, then try to update the firmware on the router in router configuration page. Given that the laptop works very well on old router, maybe the new router requires compatible firmware to allow an intense sound signal from the router again.

  Just reply to us with the State so that we can help you.

• Fast wireless is slow

  I don't understand why my wireless is sometimes slow.

  • I have it set on Channel 6, which is not used by one of my neighbors
  • I receive average speeds of 27 Mbps
  • It's a N Router with password security
  • It's nowhere near what anyone that can interfere with the signal
  • The wireless router is new
  • New firmware on router

  How will you measure the speed?

  Have you updated your wireless network card drivers?

• Reasons of OC: very slow SweepSwitch?

  I have a configured system as shown below.  GC works well most of the time, i.e. YCs every 20-30 seconds max pause about 13-15 ms, OCs every 45-60 minutes with break about 10 to 30 ms max.  KeepArea YC is 25% and GC trigger auto set to 23.4%.

  However from time to time I get a long pause in the OC.  Diagnosis of break shows that the problem is with the OC: SweepSwitch as indicated in the log below.

  According to the docs (Introduction to managing memory - release R28), OC: SweepSwitch is "a short break from the halves.  However, I have caught breaks of 5 seconds in the newspapers and other data that suggests that I had made a break as long as 10 seconds.  In these cases, I didn't have enough diagnostics to show to some that it was OC: SweepSwitch I increased progressively diagnoses, but everything I have shows that the variation in time of break is always in OC: SweepSwitch and other aspects are still within a reasonable range.

  I suspect that there may be also a very slow model OC: SweepSwitch only occurs on the first OC after the passage of genconpar to genconcon highlighted below.

  Any thoughts on why OC: SweepSwitch sometimes slower would be highly appreciated.

  If the solutions to avoid the resumption of the genconcon after a genconpar of emergency (and therefore the OC: slow SweepSwitch in this next genconcon) are:

  1. -The value XXgcTrigger: value to a higher value to avoid ever getting genconpar.  The value of this is of course conjecture based on the behavior observed worse cases.
  2. Always use a genconpar, i.e. Xgc -: genconpar instead of-Xgc: gencon.

  But the question remains, why the OC: slow SweepSwitch?  Maybe something to do with the information we need for simultaneous scanning of reconstruction lost during the parallel scan?
