• 2012 MacBook Pro running slowly after installation of el capitan

  I saw this post made by many people many times - that their computer started running slowly after the installation of the el capitan. I tried to read every post I could on this topic, and I can't find the solutions.  I was told that it could be everything from upgrading ram and an SSD hard drive, to the delivery of programs to remove the adware.  In the end, I can't understand why it runs very slowly now, the only change has been the upgrade to el capitan, otherwise everything went much before.   If someone knows a way to understand the problem or to find a solution that would be amazing!

• Query is running slowly (30 sec) first, then quickly - how to find out why?

  Hi all

  First of all, a warning: we are a company of rapidly growing software which provides a SaaS-like solution and is hosting an Oracle database for our own software running at client locations. I'm still not a DBA, but I've been learning for a while now and will follow appropriate courses, next year. This problem becomes urgent enough, however.

  We have an Oracle 12 c (12.1.0.1.7) running on a pretty Beefy hardware (card SSD 8 cores, 72GO,) and it works fine. One of our applications raise queries that run slowly very often, but when I run the same query through Toad, it is very fast again. Sometimes I can make the same query to be slow again by changing settings, adding values to an in(), etc., but not always. By not being is not in a position to know WHY the query is slow, I can not as a solution. We have been struggling with this problem for some time (more than a year, I think) and had the same problem when you still run Oracle 11.

  Some more bits of information that might be relevant:

  -This user defines cursor_sharing for force, per my request (the software itself does not lie)

  -J' put optimizer_index_caching at 25, because I know the DB all be in memory.

  -J' put optimizer_index_cost_adj at 50, because I saw full table scan too for my taste. The two parameters when it is while the queries were not already productive.

  -Memory: memory_target = 40 GB, db_cache_size = 5.5 GB, pga_aggregate_target = 8 GB sga_target = 30 GB

  -Optimizer_dynamic_sampling is the default, 2.

  -J' saw a few query plans have a note, something like "Explain plan was made with the statistics from previous executions. All do not have this, however.

  -J' saw some explain plans in which the actual recordings differ a large amount of the expected records, planned somethings was 1, real was 4 billion...

  -We actually had to add / * ordered * / for some queries to speed up execution. It's been a few other issues have better results (20 sec every time! to 200 ms), but worse when Oracle has finally found the execution plan (40ms).

  -Many queries seemed to start with arrays of harm to our taste.

  -A copy of the database, running locally, also had some problems with queries - the plan of the explain command took 2 seconds, the query itself only a few Ms. the same database of course does not receive any insert/update statements.

  It may be important to note that this scheme receives a lot of updates and inserts, so I thought that it could screw up the statistics?

  As I wrote, we have been struggling with this problem for a long, long time. We have made changes to hardware, the parameters of the Oracle, the client software, everywhere, but are no closer to a permanent solution. Any help would be greatly appreciated!

  Kind regards

  Jelmer

  Time for a summary:

  ...

  In particular the line 25 confuses me. Always this BITMAP AND even that crazy E-lines / difference A-lines. I'm sure that's the only reason for the poor performance of this query...

  I think you have a mixture of different effects here, which doesn't makes it really simple to understand exactly what is happening. To some extent this seems to be caused by the new features added in 11g and 12 c.

  1. looking at the trace of the files provided above, there seems to be some problem with dynamic sampling overload (DS). This seems to be one of the reasons why you have this "first slow exec", the second fast exec, in this case without a change of regime. In this trace file, it takes 5 seconds or more to run all these queries recursive dynamic sampling as part of the generation of the plan, and there are two DS queries that contribute significantly to that time (more than 3 seconds for these two DS queries).

  In order to have OPTIMIZER_DYNAMIC_SAMPLING 11 value causes these additional queries. The advantage of this setting is that you get good enough (join) estimates. Of course, it is difficult to judge how much you make this setting and how you lose the overhead of generating plan. New DS queries make use of the RESULT_CACHE have, in principle, reassessment of the same DS queries should come from the RESULT_CACHE. However, if your RESULT_CACHE is too small to contain all of the query results (although these result sets is usually very small) you can sometimes get slowdowns in generational terms if these queries need to be run instead of pull results from the cache.

  2. the function of vibration of statistics of course is involved and sometimes leads to a re-optimizing. Once again, this could then lead to the problem mentioned in point 1., if DS requests takes a long time to generate the plan.

  So these two functions together could lead to some difficult to predict behavior (slow first => possibly caused by DS, second time slow => caused by Feedback: statistics, leading again to DS, third etc. quick time.). It may also explain why you see 'first exec' slow, second fast exec, if re-optimizing na not take too much time and lead to a better execution plan.

  3. the special regard that seems to be the wide track as part of an internal source of lines join nested loop - and in this case, the estimates are * iterative *, so be careful when comparing E-lines (iteratively) with A-lines (cumulative across all iterations). The index used functionality combine to combine two indexes TASK_IDX1 and TASK_IDX2 suggest that it would be beneficial to add PERSON_ID to TASK_IDX1 and maybe get rid of TASK_IDX2 - but it might be appropriate to other queries, which I can't really judge. You can then check if adding more attributes to TASK_IDX1 it would make even more selective about the level of the index, as most of the lines for this particular query is filtered on the WORK table, so adding TASK level. FIXED, TASK. CLOSED and/or TASK. PLAN_START / PLAN_END it would make an even more effective operation. But adding PERSON_ID should solve this particular problem.

  4. the 'quick' this query (mentioned somewhere at the beginning) variation has no merge view inline (SELECT HELP... GROUP BY...), then you can try this by adding a NO_MERGE hint to the inline query (SELECT / * + NO_MERGE * / AID...), just to see if that gives you several times the plan 'rapid '. I still think that the index change described might be the best choice.

  5 SQL Directives of the Plan have been mentioned a couple of times, and I think that it is not quite clear to you what they are. They are not "advice", but are a new feature added to 12 c where Oracle persists some information on bad estimates and then evaluates these SQL Plan plan generation for dynamic additional sample queries and the production of statistics to create additional guidance extended statistics. I don't have enough experience with this new feature and therefore cannot judge how they play a role here. You can ask DBA_SQL_PLAN_DIR_OBJECTS and DBA_SQL_PLAN_DIRECTIVES to see if there are tickets for your particular objects in question.

• I keep getting messages "Stop running this Script?" who advise they are originally my web browser run slowly. How do I rectify this?

  It is not a clear sign of the browser slows down. It does not seem to be limited to any Web site.

  Sometimes, this problem is caused by an add-on that begins interacting with the page after most loads content, so you don't notice the problem until you get the message. Can the extension Skype Click-to-Call cause this problem.

  In other cases, the problem may be caused by the content of the page.

  If you find any model of the script that runs slowly, say Firefox? Script names that start with chrome: / / or resource: / / address either parts of Firefox or an extension. Starting with http:// or https:// usually script names are part of the site you visit.

  For more information, you can try our technical support article: script is unresponsive warning - what it means and how to fix it.

  Another good cause script errors is unresponsive on Windows Vista and newer is the feature of mode of the Flash player plugin. This feature has the security benefits, but it seems to have serious compatibility problems on some systems. You can disable it using the page modules. Either:

  • CTRL + SHIFT + a
  • "3-bar" menu button (or tools) > Add-ons

  In the left column, click on Plugins. On the right side, find 'Shockwave Flash' and click on the link for more. Then uncheck the box for "Enable Adobe Flash protected mode" and try it for a day to see if that helps you.

• Satellite Pro L300 - XP runs slowly

  Can anyone offer advice please?

  Hey mate,

  First I must say that it is really hard to say why your laptop is running slowly. There are several reasons for this problem, but it would be interesting to know if you have installed the operating system preinstalled by Toshiba or did you install XP yourself using a disc of Microsoft? In this case, you should try this again with the Toshiba recovery disc. It contains a picture of the factory settings and so, your laptop should work correctly.

  In addition, I would recommend to defragment the HARD disk, disable some services and startup programs that you don't need and you try a good antivirus like AntiVir. After that, clean you the registry with CCleaner.

  Good luck!

• Tecra A5: Publisher 2003 is running slowly and not all images will display

  I have a problem with the performance of publisher 2003 when the default printer is set to an aculaser Epson C900 since a laptop Toshiba Tecra A5.
  The editor runs slowly and has not all images. This works if the default printer is set to a different printer.
  This problem does not affect other mobile brand.

  Publihser maybe sort of speak to the printer driver and clash with another application or installed driver for the Toshiba.

  Hi Simon

  You will be very happy if someone can give you a precise answer. As far as I know, he has no problems known with Microsoft products.

  If you see the Toshiba download page you will find instructions for facilities document stating the software preinstalled on your device. It is really not known to me that some of them can cause this strange problem. I recommend contacting Microsoft support because they have more experience with own products.

  Sorry but I have no other comment on your topic.

  Good luck!

• Flight Simulator 3 and other games running slowly in Windows 7.

  Original title: Sims 3 (and other games works incorrectly) suddenly running slow.

  I'll try to make this as brief as possible while providing for.

  When I got to Windows 7, the sims 3 worked perfectly. all the graphics on the top and so on. I can't quite identify when exactly it started running slowly and I mean slow! The game, itself, does not take long to load - it never did and it's practically the only thing that has not changed. But when I go in the game (from simply create a SIM to play), that he is lagging badly. To say things to the point, the whole game is rather fluid animation as a slide show of photos.

  I uninstalled and reinstalled, but the problem persists. I've also updated my nVidia graphics card it is newer, but it did not much difference in any of the games. Sidenote: I installed the sims 2 and well there a little laggy every now and then (he's since widows xp; sure enough it's normal) it preforms perfectly. I just can't understand why the sims 3 has suddenly decided to run horribly.

  In other games, such as smaller little such as Turbo Subs, are also slow, but not to the point where I can't even play. In fact, if I play long enough gal disappears and it works normally. But I think that it may just be an incompatibility problem because part of the mine, Burger Shop 2, works very well, even better than when I got Vista. Looking for confirmation here.

  Is it possible to fix it as it used to be, or at the very least, simply reduce the amount of lag?

  Vista and Windows 7 updated drivers love then here's how update the most important.

  This is my generic how updates of appropriate driver:

  This utility, it is easy see which versions are loaded:

  -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
  For each driver in the list, additional useful information is displayed: load address of the driver,
  Description, version, product name, company that created the driver and more.
  http://www.NirSoft.NET/utils/DriverView.html

  For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
  Control Panel - device - Graphics Manager - note the brand and complete model
  your video card - double - tab of the driver - write version information. Now, click on update
  Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
  Uninstall - REBOOT it will refresh the driver stack.

  Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
  with their own software and drivers and all other main drivers that you have.

  Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
  Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
  BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

  Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
  each installation.

  Always check in the Device Manager - drivers tab to be sure the version you actually install
  presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
  in particular that) so to install a driver - reboot - check that it is installed and repeat as
  necessary.

  Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
  manually by model.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
