Bad performance with brandnew system

hello,
i set up a completely new win7-64bit based on a fresh osx (snow-leopard update) on a fresh harddisk....and i have very bad 3d performance with only 3 (!!) programs installed. i am working with autodesk 3ds max and autocad and both run very slow. my last system was win7-64bit, too, but running MUCH faster.
it must be a driver problem, but i dont know how to change the nvidia driver.
edit:
after having changed driver from directx 9 to open-gl performance is very fast.
please help.

Hi Bruno
In the following Re: Generic Sync: Object can not be deserilized / Multiple synchronization call you had mentioned that you are using MI 2.5 SP16 Client. For your information MI doesnt support Windows Mobile 5 OS on SP16 but only from SP18 does it support this OS. Have you tried upgrading the client to any of the SPs i had mentioned in the above thread and then checked the performance?

Bad performance with Payables Open Interface Import

hello all
have a performance problem with the standard program Payables Open Interface Import, as this process is taking a long time to run.
could recommend some patch for this issue or a solution.
our application is 11.5.10.2 and Database 10g
now create a SR but to date we have not been sending the first plan of action
best regards

There are many reasons this is a performance problem - search in MOS for "APXIIMPT performance" or "payables open interface import performance"
Your best bet is to work this thru an SR.
Have you traced the concurrent to determine where the bottleneck is ? Are statistics current ?

Bad performance with many xmlqueries in select and big resultset

I'm running into big performance problems with the following query (edited the query a bit to remove sensitive information):

organization_id integer path 'c:element1Header/c:organization/c:organizationId/text()',
is_sender number(1) path 'c:element1Header/c:isSender/text()')
WHERE organization_id = 5 AND is_sender = 1 AND created >= sysdate-20 AND created <= sysdate+1;This query is fast as long as the results is small (<1000), but when the resultset grows bigger, the performance seems to decrease exponentially. The cause of this slowdown seems to be in the xmlqueries; commenting out the xmlqueries makes the query very fast again (in the order of a few seconds), even with a 15000+ resultset, while including the xmlqueries makes the query take many minutes.
Workaround I tried: using a rownum < 1000 works fairly well, but only if I don't use order by (which is required). order by forces the resultset to be full built regardless of the rownum limit. (this was done with a subquery orderby and a rownum on the superquery)
Other workaround i tried: Having the subquery only return the xml column, and doing the xmlqueries in the superquery. I couldn't get this to work, something about no longer having a key-preserved table.
Background info about the database: Oracle 11.2.0.3.0, binary xmltype column, with a xmlindex unstructured component on all paths in this query, and a structured component with secondary indexes on the paths used in the WHERE (created, organization_id and is_sender). Database has about 140k records total.
My question is, if anyone knows if this xmlquery bottleneck can be remedied somehow?
Addition: graph i made indicating the performance at different resultset sizes. Horizontal axis is size of resultset, vertical axis is time spent in seconds: http://i.imgur.com/F2tyg.png

Bad performance with PreparedStatement

Hi,
I have a query that returns about 10.000 results on which I have to iterate.
The query is something like that :
SELECT col1,col2 FROM myTable INNER JOIN myTable2 using(id) WHERE time > TO_DATE('15/06/2009 16:28:00','DD/MM/YY HH24:MI:SS') AND time < TO_DATE('16/06/2009 2:35:00','DD/MM/YY HH24:MI:SS');
This query is ultra fast using a basic Statement, It iterate over all line of the cursor in less than 100ms.
The date parts of the query are generated using string concatenation.
Since it's a bad practice I have decided to use a PreparedStatement and so to change the query like that :
SELECT col1,col2 FROM myTable INNER JOIN myTable2 using(id) WHERE time > ? AND time < ?;
I bind the dates and I get exactly the same result, except the performance... Now it doesn't take 100ms... It take about 120000ms (2min)!!!?
The execution of the query is not the problem, the problem comes from the ResulSet.next() method that is much longer than before.
I precise that the exactly same values are used, the result is exactly the same.
I have tried different value for the fetch size but no big differences.
An idea?

Sorry I have answer too fast. I have still performance issue when using the query :
SELECT col1,col2
FROM myTable
INNER JOIN myTable2 using(id)
WHERE time > TO_TIMESTAMP(?,'DD/MM/YY HH24:MI:SS.FF')
AND time < TO_TIMESTAMP(?,'DD/MM/YY HH24:MI:SS.FF')
PreparedStatement stmt = connection.prepareStatement(
SimpleDateFormat sf = new SimpleDateFormat("dd/MM/yy HH:mm:ss.SSS");
stmt.setString(1, sf.format(fromDate));
stmt.setString(2, sf.format(toDate));while the following query perfectly work :
SimpleDateFormat sf = new SimpleDateFormat("dd/MM/yy HH:mm:ss.SSS");
SELECT col1,col2
FROM myTable
INNER JOIN myTable2 using(id)
WHERE time > TO_TIMESTAMP('" + sf.format(fromDate) + "','DD/MM/YY HH24:MI:SS.FF')
AND time < TO_TIMESTAMP(('" + sf.format(toDate) + "','DD/MM/YY HH24:MI:SS.FF')Really bored of oracle products...

Bad performance with non-cumulative key figures

Hi All,
I have a cube with 8 non cumulative key figures based on fiscper.
I am not sure how the performance for reporting with non-cumulatives can be improved.
Thanks
Karen

Performance of non cumulative cubes is dependant on the distance between the marker (date of the last compression) and the execution date.
For actual stock, the more you compress the better it is.

XML Publisher has bad performance with 10 concurrent users.

PeopleTools version:Tools: 8.48.09
OS/RDBMS Version*( required for Tools Forums): Oracle 10.2.0.4
Application type and version:
Description of the Problem/Question:
Customer currently testing a process which exposes XML publisher functionality via self service. The process calls an app engine which
generates an XML file, processed by XML Publisher, and then displayed in the browser window.
They have found that any more than ten or so users in our test environment (two app servers, one web server per app server) seems to slow
the process to a halt, even causing some requests to go unprocessed. The bottleneck seems to be at the web server (WebLogic) as the
database and app server performance metrics are very good, however PeopleSoft Ping suggests that the web server is having trouble.
production environment has 8 app servers, one web server per app server. Are there any configuration changes we can make to improve
the serving of PDFs from XML publisher output? Add more web servers per app server? WebLogic java VM heap settings?
WebLogic Server 8.1 SP5
Tuxedo: Version 8.1, 64-bit, Patch Level 192
Any other thoughts on performance degrade with XML Publisher with more than 10 users.
Are there any configuration changes we can make to improve the serving of PDFs from XML publisher output? Add more web servers per app server?
Thanks

There are currently two known operations that are seriously slower in update 10:

You can disable the hardware pipeline to basically go back to the old situation as it was in update 7 if it is giving your problems. I wouldn't know why simple fill actions would be bogging it down though, it smells like something is done wrong in your app.

Bad Performance with Oracle Lite 4.0.1

I have a table in Oracle Lite with 17000 records and 110 fields. A SELECT on this table needs 1 minute to finish. The same table and query only needs 1 second on Oracle 8i Server. MSDE also needs 1 second. All the relevant fields are indexed. Are there any parameters in Oracle Lite that we can tweak? Is there something else I'm forgetting?

Hi Shivek,
An excellent solution for this is provided in the metalink Note:455905.1.
Let me know if you have more questions.

Bad performances with both catalyst and free driver

Hello,
With the catalyst driver 15.20 and Xorg 1.16 my graphic card(hd 7870) is not used at her maximum for example in kerbal space program i have beetween 45% and 88% Gpu load but only in place like oceans normaly it don't exceed 75%, i have the same issue in war thunder,star conflict,robocraft but with unigine benchmark's (valley and heaven) it is good. I dont think it is normal . The cpu isn't overloaded it is a i5 3570.
What can i do?

Very Bad performance with high stress on Tempdb

Hello ,
below is the execution plan for a query rapidly increase the Tempdb and has very slow performance,
appreciate your suggestion to enhance this query (any data is available upon request)

>Covering indexes will make a huge difference.
You can't simply "create-covering-index" yourself out from every performance jam.
Questions:
Is the query important enough to justify special consideration?
How many covering indexes?
What is the performance impact of the new covering indexes on other queries?

Bad performance with graphic glitches running intensive OpenCL software

Under Yosemite Cinema 4D R16 (while R14 is works well) and Autocad for Mac 2015 (with all the previous releases) are affected by horizontal pixelated artifacts (not properly glitches by very near to be); and again iTunes library seems to be affected by horizontal portion of the library by the same glitch when you scroll down (it disappears after log out). Someone refers these issues to Vsync (that autodesk softwares make Off) while to me it seems clearly incompatibility drivers with Yosemite and last version of these softwares. My configuration is NVIDIA GeForce GTX 780M 4096 MB and mentioned softwares were fine under Mavericks and with the same Hardware...

Bad performance on system, export/import buffer many sawps

Hello,
I have an ECC 6.0 system on AIX with 6 application servers. There seems to be a performance problem on the system, this issue is being noticed very well when people are trying to save a sale order for example, this operation takes about 10 minutes.
Sometimes we get short dumps TSV_TNEW_PAGE_ALLOC_FAILED or MEMORY_NO_MORE_PAGING but not very often.
I am not very good at studying the performance issues, but from what I could see is that there are may swaps on buffer export/import, program and generic key. Also the HitRatio is 88% at buffer export/import, which I think is pretty low.
I know that the maximum value accepted of swaps per day is 10000, is that right?
Can you please advice me what needs to be done in order for these swaps to decrese and hit ratio to increase? And also what else I should do in order to analyse and root cause and the bad performance of the system?
Many thannks,
manoliv

Hi,
sappfpar determines the minimum and maximum (worst-case) swap space requirements of an R/3 application server. It also checks on shared memory requirements and that the em/initial_size_MB and abap/heap_area_total parameters are correctly set with the following procedure:
/usr/sap/<SYSTEMNAME>/SYS/exe/run/sappfpar check pf=/usr/sap/<SYSTMENAME>/SYS/profile/<Profile name>
At the end of the list, the program reports the minimum swap space, maximum heap space, and worst case swap space requirements:
Additional Swap Space Requirements :
You will probably need to increase the size of the swap space in hosts in which R/3 application servers run.
As a rule of thumb, swap space should equal
3 x Size of Main Storage or at least 1 GB, whichever is larger.
SAP recommends a swap space of 2-3 GB for optimal performance.
Determining Current Swap Space Availability: memlimits
You can find out how much swap space is currently available in your host system with R/3s memlimits program.
Heres how to run memlimits:
From the UNIX command prompt, run the R/3 memlimits program to check on the size of the available swap space on the host system on which an R/3 application server is to run.
The application server must be stopped, not running.
/usr/sap/<SYSTEMNAME>/SYS/exe/run/memlimits | more
The available swap space is reported in the output line Total available swap space: at the end of the program output. The program also indicates whether this amount of swap space will be adequate and determines the size of the data segments in the system.

MBP Retina low performance with external displays

Hi everyone!
I have a very bad performance with my MBP 15´´ retina display when it comes to ad an external display. I have a FUL HD LG monitor that looks very bad when i connect the HDMI or the thunderbot port with the proper adapter (as bad as you can´t even read). I want to know if this may ba a hardware problem just with my computer or if it is a software problem, any ideas? does anyone have the same issue?
How can i update my NVIDIA card???
Thanks a lot!

Topic seems to come up here often. Apple has a tendency to dismiss the issue.
Its a pretty well known problem that Mac font smoothing doesn't seem to work well on high resolution third party external displays, making text hard to read. In addition, I think the Mac HDMI resolution support is limited to 1080p, so you must use DP or DVI video interfaces to see full monitor resolution.
The OS default is no font smoothing on external displays (except perhaps the apple display). There is a terminal command that will enable font smoothing for any external monitor, but it often doesn't work well enough. I found that using the OS zoom feature magnifies text to the point to be easily readable. You can set zoom parameters in the accessibility systems preference panel.
For some reason, sometimes the Mac OS thinks some monitors are TVs and use YCbCr instead of RGB. You can open the color sync utility and brouse the settings to see what is being used. There are scripts available that can fix that but are more complicated to install than an app.
It seems that PCs are way ahead of Macs with external display implementation. Most folks having monitor problems with a Mac do not see the same issue with PCs or Unix/Linux OSs.
Oh as far as updating the video card, can't. The monitor "drivers" are built into the OS. When a new display is connected, the OS finds the profile for it.

Bad performance when deleting report column in webi(with "Design – Structure only")

Hi all,
One of our customer has recently upgraded from BO XI to BO4.1. In the new BO 4.1, they encountered a bad performance issue when they were deleting a column in Webi(using "Design – Structure only" mode).
With “Design – Structure only" mode, it took webi about 10 seconds to complete after the customer right-clicked a report column and clicked the "delete". The customer said that they only need to wait for less than 1 second when they did the same in BO XI old version.
The new BO version used is 4.1SP02, installed in Windows Server 2008 R2. (Server with 32 core CPU, 32G memory)
This bad performance happened in both Webi web and Rich Client. (in Webi Rich Client, the performance is a little bit better. The 'delete column' action takes about 8 seconds to complete).
Do anyone know how to tune this performance in webi? Thank you.
Besides, it seems that each time we are making change in the webi report structure in IE or Rich Client, webi need to interact with Server site to upload the changes. Is there any option to change this behavior? Say, do not upload change to Server for when 'deleting report column', only trigger the upload after a set of actions(e.g. trigger when click the "Save" button).
Thank you.
Regards,
Eton.

Hi all,
Could anyone help me on this? Thanks!
What customer concerns now is that when they did the same 'column editing' action in BO XI R2 for the same report, they did not need to wait. And they need to wait for at least 7-8 second in the BO 4.1SP02 environment for this action to complete.(data already purged, in structure-only mode)
One more information about the webi report being editing is: there are many sheets in the report(about 6~10 sheets in one report). Customer don't want to separate these sheet into different reports as it will increase the effort of their end users to locate similar report sheets.
Regards,
Eton.

Performance with external display

Hello,
when I'm connecting my 19'' TFT to the MacBook the performance (with the same applications runnig) is realy bad. It tooks longer to switch between apps and if I don't use an app for some time, it can took up to 30 sec to "reactivate" the app.
Because the HD is working when I switch apps, it looks like the OS is swapping. My question: Would it help to upgrade the MacBook to 2GB ram? AFAIC the intel card uses shared memory.
Thanks for your help
Till
MacBook 1.83 GHz/1GB Mac OS X (10.4.8)

How much RAM do you have? Remember that the MB does not have dedicated VRAM like some computers do and that it uses the system RAM to drive the graphics chipset.
I use my MB with the mini-DVI to DVI adapter to drive a 20" widescreen monitor without any of the problems that you describe, but I have 2GB of RAM. If you only have the stock 512MB of RAM, that may be part of what you are seeing.

Extremely slow performance with Radeon HD 7870

Hi,
I am using a number of Adobe programs on my new Windows 8 64 bit system, with 16 gigs of ram, an Intel Core i5 2.67ghz, and AMD Radeon HD 7870 2 gig. All the programs (including After Effects and Illustrator) work very well with the exception of Photoshop CS6 64 bit, which has extremely slow performance with Use Graphics Processor enabled in my preferences (which Photoshop selects by default). If I turn off Use Graphics Processor, the slow performance vanishes. If I change Drawing Mode to Basic, there might be a slightly detectable improvement over Normal and Advanced, but it's still horribly slow. The refresh rate seems to be just a few frames per second. Everything is slow: brushes, zooming, panning, everything.
I've tried changing the settings I've seen suggested elsewhere: I switched Cache levels to 2, history states to 10, and tile size to 128k. No effect. Photoshop is currently at the default of using 60% of available ram. Efficiency has remained at 100% throughout all my tests. Also, this slow performance has affected me from the moment I installed Photoshop; it didn't crop up after previous good performance. The problem exists regardless of the size or number of documents I have open. Performance is still terrible even when I create a 500 x 500 pixel blank new canvas and try a simple task like drawing with the brush.
Photoshop is fully up to date, and so are my graphics drivers (Catalyst version 13.1). Any help would be greatly appreciated; at the moment performance is so bad in Photoshop that it's unusable with graphics acceleration enabled. Thanks in advance for replying.

Great news!
I followed your suggestion, Noel, and uninstalled my drivers with the Catalyst Uninstall Utility (which I hadn't used before), rebooted, reinstalled Catalyst 13.2 Beta 7, rebooted, deleted the PS Prefs, started PS, and now the performance is radically improved!
It baffles me why I would need to do a clean driver uninstall in a new system environment that has only ever had this video card, and is only a few months old, but that action seems to be what's improved the situation. Note that because I deleted the PS preferences, the good performance now occurs with the default Use Graphics Processor enabled, and Drawing Mode set to Advanced (with every feature in the Advanced dialog checked except 30bit display).
Having no reference point, I can't tell for sure if performance is as good as it theoretically ought to be for my system specs, but using the standard 13px brush is only slightly laggy behind the cursor, even if I become reckless and squiggle on the canvas violently. It wasn't just sluggish response before: Photoshop seemed to be in pain trying to draw the line segments as it laboured to catch up to the cursor. That is pretty much gone now.
Much more tellingly, zooming and panning the canvas is like it ought to be, responsive and clean, more or less like it was for me in CS4 with my old Nvidia 9600GT. The poor performance with zooming and panning was the most worrying aspect of the issue. It's a great relief to see these working more properly now.
I have to confess I'm a little embarrassed to have drug you through all this hassle only to discover that something as rudimentary as properly cleaning out the drivers would be the apparent solution. I never would have imagined that doing that, with such a new and stable system, would make any difference, since I don't have a legacy of older drivers dotting my hard drive. In any event, I'm really grateful that you guys took the time to try to help me.
In the interest of completeness, here's the relevant portion of my system info after doing the reinstall steps I mentioned above:

As you can see, the Microsoft Basic Render Driver still appears as a Video Card in the list. This presumably has something to do with Windows 8, and I really don't know if its presence here is still a sign that my card is not being used to its optimal capability. I have a hunch that the slight lag that I am still experiencing with the brush when Use Graphics Processor is on -- totally absent with the acceleration turned off -- implies that Photoshop is still unable to take maximum advantage of my card. I would assume that the brush tool should be more responsive with acceleration on than off, in a rig without any issues, but that's just assumption on my part. If you turn off Use Graphics Processor on your systems, is the brush tool more or less responsive?
But again, panning the canvas with the hand tool is now extremely responsive, without any screen tearing or visible lag, and that's a massive improvement over the total meltdown of performance I was suffering from before.
Thanks again very much for your help. I'm grateful to all of you who took the time to chime in.

Bad performance with brandnew system
