Playback of a view is much slower than reading the table

Hello

I use the view in the physical layer. Query from this point of view is quite compilcated. However if I use correct filters the result is very fast (a few seconds)

Responses of dashboard if I put a few columns from this point of view, and use the same filter, to 4 to 5 minutes to get the result. I don't know why the reading of the opinion is so slow on dashboard.

If I create a table based on the view and use this table in the physical layer, then the result is much faster.

Thank you

Hello

When the function u view the report in the bi bottom server sends the request to the database (if the cache is disabled).
Come see, you already mentioned this query view is quite complicated, fires every time the query whenever you click on the report and checks all aggregations, the filter conditions, and joins.
come to table, you are calculated and stored, each time that you run the report he just send the query like Select from table *.

for this reason, the data view recovery is slow to table.

See you soon,.

  • Guest WiFi network much slower than normal on the network

    Speedtests leave a device attached to the 5 GHz wireless guest network are much slower than when the same device is connected to the normal 5 GHz WiFi.

    I measured reproducible all about 7ms 18/10 down on the network of comments and 1ms 320/250 Mbps on the normal network. Same place, same camera, same speedtest app, same test server.

    Similar results of multiple devices (laptop, Windows, iPhone 6 s). No change after a reboot. QoS is off. Firmware is 1.0.6.28_1.1.83.

    What could be the reason? I don't think that I had the same problems a few months ago, but I has not changed settings since then, except for the upgrade of the firmware when a new version appeared.

    Thanks for your advice.

  • The repeated CFC function call is much slower than the UDF version

    For a project, we were faced with unexpected behavior of a CFC. Without going to much into the details of the project, it boils down to the following: when we run through a set of records, say 100 and apply a function to this topic, the overhead is 4-5 seconds extra when we call it a component instantiated (only once) compared to when code us as a UDF. Since our application can process thousands of records in 1 past the overload will quickly over 100 seconds compared to the UDF.

    I was wondering if there is no logical explanation for this behavior. From what I understand a function called from a component should not add any notable overload after the component was instantiated.

    Our installation is an installation of Coldfusion 8 Jrun running on Linux. We didn't really find anything on the web documenting this (or we found we have said that there will be no additional charge). We could modify the function call to a call from the UDF, but we prefer to keep in a CFC as there are more things behind the scenes that just formatted data.

    HA!  Cool!!! I think I solved it something, I feel so proud.

    I run the code of Adam and the first time I ran it I got similar to Biebel3 results.  But it's curious, I got the output of debug it showing that it wasn't show where the time was spent.  He would show almost two full seconds to build the page of CFCS, but the components in the table of debugging only added up to about 50 milliseconds.

    I tired first put a top of the page of CFC, but that has not changed the results.  Because even if you do not display the results, ColdFusion still satisfied the debug output.  I went into the administrator and effectively disabled the debugging feature.

    Alto, I started to have the results displayed by Adam.

    It seems that it is a question where it takes a lot of overhead for ColdFusion compile a record of debugging for each call of CFC in this large loop.

    The good news, this is a pretty easy solution for a production system.

  • Alt in CS6 dropper is slower than on the earlier version?

    Hello

    I'm used to paint by clicking quickly drops alt eyepieces and paint in quick succession. Its been my method of paint on all the photoshop to CS4, I just moved to CS6 and a very annoying bug prevents me from doing this effectively.
    When eyedropping there will be a small delay after selecting the color where, if I click again to paint I will get sound windows burst like it was currently impossible to paint. If I wait half a second after picking, I can paint well, but this slight delay is enough to drive me crazy and really slow me down since I do, I don't know, 2000 + brush STROKE / day. No idea what causes the pipette to be slower than before? I disabled the color ring which was new to me, but that didn't fix it.

    I think that I found a solution to the question of drops eyepieces.  He solved the problem in my case, I hope that it will work in your case also.  It ends up being a conflict of Windows and is not a problem with Photoshop... Sorry Adobe.

    Do the following-


    Control Panel-

    Stylus and touchscreen.

    'Click' on ' hold down / right click»

    Turn off press and hold for right-click

    * I also disabled use of the stylus button as a right-click equivalent

    There is no slowdown problem now with the pipette for me, or have the pipette don't pop up at all when I hit the ALT key .

  • 1.5.4 - slow to expand the tables for oracle 9 connection

    Hello

    I have tried version 1.5.4 and have found that in developing the node tables in the Connections tab is extremely slow (about 3 min) for my oracle 9.2.0.6 connections.

    As with this [this bug: http://forums.oracle.com/forums/thread.jspa?threadID=867600 & tstart = 0] it's ok on a 10.2.0.3 connection.

    Expand the tables for the same connection in 1.5.3 is good too. I'm concerned that this latest version of the sql dev was not particularly well tested with oracle 9 abit.

    Oracle 9 is still a supported with sql developer version?

    Thank you

  • Development of 2d - performance (much slower than 9000 9500) games


    Not really a player, I don't think it will be very useful, and it's entirely anecdotal, so I would not base your decisions on that, but maybe this will help you.

    Regarding the "power" of the various models of Blackberry, you could search the Internet, looking for the processor that is used as an indicator of the power.  BBs of Java didn't have (at least as I understand it) a graphics processor, then all the image processing is done on the main processor.

    You will find if you look at this page:

    http://en.Wikipedia.org/wiki/BlackBerry_Bold

    that the 9000 has a 624 MHz Marvell Tavor PXA930, while you are looking for here:

    http://en.Wikipedia.org/wiki/BlackBerry_Storm

    your Storm has a dual core CPU 400 MHz and ARM9 274 MHz ARM11

    Using the cycles in comparison, it would mean for me during the development of a game, it'll be quicker on the 9000 the storm, because I believe that the treatment of Java is in fact all is done on a single processor, if your painting will be restricted to the 400 Mhz on the storm.

    My experience is "BOLD" seems faster than the storm in general, but I actually always put that down to the bigger screen being slower to draw.

    In terms of processing power, the phone slower that I think you could develop to is in fact the storm, but actually I would not develop for it.  It has a system with a somewhat strange interface because of the screen push.  I would ignore this device and just concentrate on OS 5.0 devices.  To this end, the slower device is probably the Blackberry Curve 8520, with a 512 MHz processor.  I would get one of these for your tests.  Also, the (screen size, keyboard) form factor is shared by a large number of other phones.

    In general terms, my brief experience with treatment of the game showed me that if you want your game to go fast, be updated too little screen that you can.  So use 'regions' in your paint method to specify exactly which pieces on the screen should be updated.  In my tests, I tried to have a cursor to move around the screen using the trackpad.  If I moved the slider and then redisplays the whole screen, the performance has been extremely slow.  But if I just painted on the slider of the region it's in, and he painted in the apartment that he had moved, I got a slider action much, much more flexible.

  • Why my iMac 4K (late2015) runs so much slower than my MacBook Pro 128SSD (end of 2012)?

    Both are basic model, without Add - ons or updated, the new iMac, retina display 4K runs as slow as some laptops HARD drive.

    What is the defect of manufacturing for my iMac? Any idea?

    Thank you.

    Your Mac has a Fusion (mixture of Spinning/SSD HD) drive, or is it totally SSD? How much RAM you have installed on the iMac over the laptop?

    You can download and run EtreCheck and post the contents of his report here and someone can spot something that could be the cause of slowdowns:

  • Why Firefox MUCH slower than the 8.1 9.0? Just downloaded and tried and am used to dramatic improvements instead!

    It's a fact! Web pages load much more slowly, and I deleted the cache and done all the typical checks of my pages frequently visited with the same result.

    I just found the problem. For some reason, when I upgraded to 9.0, the settings in tools/options have been modified in the section on how Firefox connects to the Internet. I found to be returned to: 'use the system proxy settings' when I had previously put in "no proxy settings." Once I changed back, the speed is back up on top of the browser and everything checks very well now. Just in case you guys that see happen, then check this particular setting.

    In my situation, I am just connect to Sprint broadband with card data and did not the routers or network worry except that Windows 7 has implemented when I update software Sprint from time to time. This suggests that maybe Firefox 9.0 was just delivered to this particular my computer configuration, although it worked well like that. I hope this might help someone else!

  • WRT310N - Tests of speed than 802.11 g or 802.11n are MUCH slower than Ethernet

    Hello. I have a WRT310N router connected to a cable modem. Because my internet connection is capped at 16 Mbps, I wait like http://speedtest.net/ speed tests and http://www.speakeasy.net/speedtest/ are very similar on Ethernet and wireless.

    The results more wireless are extremely poor (less than 1 MB/s) but via Ethernet, they are all around 16 Mbit/s.

    I first noticed questions during video streaming on Netflix HD for my XBOX 360 more 802.11n. My internet connection is fast enough for this, but not the video downgrades. This is clearly a problem with my wireless setup, but I don't know why it is so poor.

    Any suggestions are greatly appreciated.

    Thank you

    Disable the made frame burst and also reduce the MTU to 1365 on the Configuration tab and click on save settings... Now, cycle power to the router and check... If this makes no difference then, try upgrading/re-flash firmware of the router and re-configiure the router from scratch.

  • Why is my wifi connection much slower than my 3G connection?

    I lot to access web pages when connect you via wifi. I am connected to my wifi network (at least he shows on the Meadow). Simply, it seems to load forever or expires. Sometimes, it will connect (perhaps only 10% of the time). No other problems with the other computers on my network.

    When I'm on 3g it is lightning fast. So for now I just turn off wifi.

    Any suggestions?

    Since the browser if you go to the options by clicking on the Web tab in the top left, then Preferences, you can clear history, Cookies and Cache. Maybe try that.

  • T500 T8700 processor work much faster than on the current of a battery!

    My colleagues and I are having a very annoying problem with our thinkpad t500 (approximately 200 laptops or more). the problem is that the CPU is intel core 2 duo T8700 2.53 ghz works only with 1.6 ghz speed on idle and load the State with alternating current and never jump higher than speed and jumps only to 2.53 ghz speed if and only if the battery is connected to the laptop, the laptop is faster using the battery that is strange indeed.

    My own opinion on this issue, it is that it is a bug in the bios that is the switching in a different way processor modes (processor with power supply ofc should be faster than with battery) I've already updated my bios of the laptop to 3.09 version, but always without success. The serial number of my laptop is "*".

    I hope that fix you this very soon.

    Moderator edit: number masked to prevent improper use.

    Hi mtaher and welcome to the Lenovo user community!

    Connected to a 65W power adapter, the T500 is relies on the battery to power during peak load. If you remove the battery, he's choking back the CPU at a level that the 65W adapter can handle alone. It probably won't happen if you use a 90W Adapter (I don't have anyone around to test - maybe someone can confirm).

    The research community and you will find this discussed many times - that's the behavior designed most of the models.

  • Why is slower than on the glDrawElementsInstanced iPhone6 glDrawElements?

    When draw the fate of trees or flowers, we try to use instantiated drawing, since the objects differ only by their matrices to model.

    However, we noticed that on the iPhone6 and iPad Mini 2/retina that performance degrades when using instancing compared to several batches of drawelements. Other systems that we tried on responds very well to drawing instantiated, so it is a bit strange.

    Is this a known problem which does not support the iPhone6 instantiated drawing correctly or is it not that we missed to activate something or similar?
