Bad Desktop Performance with Dell P2715Q

Hi everybody,
I'm using a 15" Mid 2010 Macbook Pro with the following specs:
- 2.4GHz i5
- 8GB 1067 MHz DDR3
- Samsung Evo 850 (250GB) as Startup Disk
- GeForce GT330M 256 MB
- External Dell P2715Q with MiniDP to DP cable at 2560x1440
- Yosemite 10.10.2
- External Keyboard and Mouse, both wired
Unfortunately (apart from my Graphics Card being unable to output 4K but I accept that, this machine is almost 5 years old) the performance when using normal desktop operations is really bad on the Dell monitor. Some things like scrolling in Finder and Safari work fluently, but most not. Here's a list:
- Minimizing and maximizing, moving and opening windows is lagging
- Horrible video performance when watching Youtube HD videos, especially in fullscreen. Sometimes nothing happens for more than 5 seconds, screen simply freezes
- Lags when using some third-party apps even when only scrolling through text (for example Matlab)
When the issues above appear, the process WindowServer has a very high CPU usage, my computer starts to heat up and burn enormous amounts of energy, gets unusable. I googled the issue with the WindowServer and followed the advice, reducing the transparency helped a little but especially the issue with Youtube videos is unchanged. Even when doing nothing, the CPU usage of the WindowServer never drops below 0.5%. In general, the experience when working on the external monitor is kind of slow and really unsatisfying, different then what I'm used to from the Macbook. From the 8 GB of RAM I have, 5.7GB are used when simply typing this text in Safari apart from having Outlook and a terminal open (plus some background apps like Dropbox).
Things are a little better when working in closed-clamshell mode (mostly the issues with handling windows, HD video in fullscreen still *****).
The only things I haven't tried is resetting the SMC & PRAM since users reported that doing so doesn't help at all.
Any help would be highly appreciated.
Edit: My Yosemite Installation is a fresh and clean installation, nothing was transferred/proted from an older Mac OS installation, apart from some documents of course

Well it obviously supports the resolution (also according to the datasheet) and playing HD video at lower resolutions works fine.. I just saw this:
2014 Macbook Pro 15" doesn't work well with 4k @ 60hz, obvious lag due to high WindowServer CPU utilization
which makes me think that it's not really a performance thing but more a bug in Yosemite.

LabVIEW performance with Dell Integrated DVMT

Anyone have any experience with this? My company doesn't want to spring for an 'extra' video card. Rather, they are prescribing Dell's Optiplex GX260 with'Integrated Intel Extreme Graphics', which has no dedicated Video RAM, but uses up to 64MB of system RAM instead. This seems like a bad idea to me from a LabVIEW performance standpoint. Recommendations? TIA.

That was not a wise move, to exchange the Quadro K5000 for an outdated and slow Quadro 5000. Even a $ 180 GTX 660 is clearly faster.
What can cause the behaviour you see?
Unusual codec in your source material. It has weird dimensions and is extremely compressed.
You don't use MPE accelerated effects.
The export settings don't use hardware MPE.
You use only 16 GB memory and a single CPU at standard clock speed.
Try the PPBM5 Benchmark to see how your system performs. With that info you can get better insight into whether something is ill configured or not.

Bad Airplay performance with Macbook Pro (10.9.4)

My iPhone and iPad delivers Airplay (almost) without problems to my NAD D7050 receiver. But music sent from my Macbook Pro Retina running 10.9.4 lags so much that there is no use in it. Please advice.
Thanks

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?

Dell Dimension 5150 Desktop fitted with a Cohiba w...

Evening all,
I have a Dell 5150 desktop PC with a Cohiba 3887 USB wifi adapter fitted, when I boot up the PC and login, the adapter status is "connected to BT Homehub 2 - TRT2", after about 1 minute the status changes to "unable to connect to your preferred wifi networks". If I then go to the wifi network list and connect manually everything is OK, how can get the adapter to connect automatically. I've had a look at the network setting (several times), the homehub is set to automatically connect, tried changing some of the settings but no joy. Thanks.
O/S Windows XP Pro.
Memory 3GB
Pentium D 2.8 Ghz
Solved!
Go to Solution.

Thanks for your reply, I've changed the HH setting to b/g, no change. It looks as though there is a conflict between whatever is connecting the adapter during bootup (BT wireless manager?) and when windows tries to take over and connect to "preferred networks", if I take windows out of the mix by disabling "let windows manage your network connection" in the network settings, it will auto connect to BT Fon, which is not in my preffered network list (only the BT Homehub is) but BT Fon is in my "available network list"........Confused? I certainly am!
The Cohiba driver was installed about a year and a half ago, just before they stopped supporting the adapter, consequently no newer driver available but the adapter does work OK once I've manually connected it.

HT202856 Dell P2715Q for 2013 Mac Pro.

The new Dell P2715Q 4K monitor looks to be a technically compatible monitor for the new Mac Pro. I see it supports DP 1.2 and MST.
Anyone using this monitor and and vouch for its use.
Thanks.

Hi,
I just setup a pair of these P2715Q monitors with my 2013 MacPro using the supplied MiniDisplayPort to Displayport cables. The screens look fantastic. The main issue I'm having is after restarting or cold starting the computer. Both monitors appear and only show a blank desktop. No menu bar, no Finder icons, etc.
The only fix so far is to power off one of the monitors - then back on. Then all is fine. I've unchecked the Mission Control thing to allow displays to have separate spaces. On a normal startup - the second monitor is usually just a blank desktop. It's like they are both showing that blank desktop.
You mentioned you were having similar issues. Any other resolution to this?
I ordered a pair of minidisplayport to minidisplayport adaptors to try - incase the rub is with the included cable configuration. I've tried resetting PRAM, NVRAM, etc. - Tried different thunderbolt ports.
Actually - when trying different thunderbolt ports - things got wonky in that the second monitor stopped being acknowledged by the computer. I kept moving the thunderbolt cable around - then it finally came back on. Not fun.
Another strange issue yesterday was when I sat down to work - both monitors were in sleep mode (computer still running though) - the primary monitor wouldn't activate. Even after a restart. I couldn't even power cycle the monitor with the power button. I ultimately had to pull the power cord on the monitor to get it back. Again... not fun.
One thing to note as well - My primary monitor is Rev 01... the secondary was built 2 months earlier and shows Rev. 00. I'm waiting for them to replace the second monitor. These guys update the firmware and other items and never tell anyone what's changed. But I sure want the most current build.
Any thoughts? - I'm running 10.10.2.
Thanks,
Sam

CS4 poor dialog window performance with huge screen dual 30 inch

Hi, I am running dual 30 inch monitors each one at 2560x1600 resolution, on windows xp sp3 on an nvidia quadro FX 3700M (dell precision M6400 laptop)
If I use CS4 from the single laptop screen, everything is fine. However, whenever Im on the huge dual screen desktop any dialog box activity has a very poor performance. For example, I select File>New and the dialog window takes some two to three seconds to draw on the screen... it might not seem like a big problem but it is very very annoying since I am used to the snappy response of the user interface from years of PS use. It really affects my workflow since I work with many files at the same time.
Also, the bigger the dialog window the slower it takes to appear. If I select File > Save for Web and Devices, that dialog window will take up to five seconds to appear on the screen.
The problem seems to get worse the longer the OS has been working, ie. if the PC is freshly booted the problem seems a bit lighter. So it might be related to video card memory or something.
Here's what I have tried so far to solve this:
Since what I'm using is a laptop, the driver choices are limited, however I've been able to force install the 181.20 version of the nvidia driver, but it made no difference. All the official driver versions (176 series) from Dell also have the problem.
The problem doesn't seem related to Photoshop's use of the GPU as the problem remains while the GPU acceleration disabled.
This problem is also present in PS CS3 as well as CS2 CS1 and version 7 which are all I am able to test.
I was able to reproduce this problem on a desktop computer with the same setup on an nvidia quadro FX 5500 card. The dialog box window performance is really terrible.
I did not notice this problem in any other application that spans the two screens, even high end 3d ones.
Ok well it seems from my testing that Photoshop is simply bogged down by having such a huge desktop area to work with. It is really disappointing since PS was my only reason to spend so much money on this dual 30 inch screen setup.
Has anyone else noticed this? Are there any other suggestions? Any adobe support on this?
Thank you

I have tried with both open gl enabled and disabled (edit > preferences > performance)
The problem is present even in Photoshop version 7, I think that one didnt even notice the presence of a 3d accelerator chip.
Both video cards tested have 1GB of video ram.
Thanks.

Is Creative Sound Blaster Audigy 2 NX USB sound card compatible with Dell deskt

Im considering buying the Creative Sound Blaster Audigy 2 NX USB sound card to use with a Dell desktop XPS 40, but recently read a forum message on another page that there was a issue with installing on a Dell Tower but no problems with installing on a laptop
any help is appreciated if there are any compatibility issues with using this sound card on a Dell desktop, Thanks
the main reason I would like to upgrade to this card is so my pc doesnt use the integrated audio which Id like better quality performance with a sound card and also dont want to install a internal card on the system

joaolfb,
Audigy 2 NX will need to be connected with the power adaptor inorder to run. USB will not be enough to sustain the power consumption of the sound card.

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

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.

Remote Desktop Access with Mac and Asus Transformer Prime

I have an E2000 router with the most current firmware. I have a Sony VAio laptop with Windows 7 Home Premium 64bit,a Macbook with 10.6.8, and a new Asus Transformer Prime with ICS.My work desktop is a Dell Optiplex 380 with Windows 7 Pro 32bit. I frequently work from home and have no issues remoting into to my work PC from by Sony laptop via VPN and RDP.However I have never been able to connect successfully to my work PC with my Macbook(using Remote Desktop Connection 2.1 for Mac OS) or Asus tablet(using WYSE Pocket Cloud RDP app for Android). I can however connect to the VPN itself on the Macbook and tablet without issue same as my Windows laptop. The other interesting part is I can connect via RDP when I am connected to a Mi-Fi 3g hotspot. So it is definitely something in the my Linksys E2000 blocking the connection for some reason. I have even set Port forwarding of 3389 with the ip's of both the Macbook and Asus tablet.I have also tried connecting via ethernet to the router with the same outcome. I cannot ping my work pc from either device as well.In addition the firewall on my work PC is completely disabled and all services related to Remote desktop access are enabled and running.Does anyone have any ideas?

For my tablet its own ip assigned by the router. Same with the macbook.the Pocketcloud RDP app also uses 3389.I have port 3389 set for both internal and external port and protocol "both" under the Single Port Forwarding tab in the router config.

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 INSERT performance when using GUIDs for indexes

Hi,
we use Ora 9.2.0.6 db on Win XP Pro. The application (DOT.NET v1.1) is using ODP.NET. All PKs of the tables are GUIDs represented in Oracle as RAW(16) columns.
When testing with mass data we see more and more a problem with bad INSERT performance on some tables that contain many rows (~10M). Those tables have an RAW(16) PK and an additional non-unique index which is also set on a RAW(16) column (both are standard B*tree). An PerfStat reports tells that there is much activity on the Index tablespace.
When I analyze the related table and its indexes I see a very very high clustering factor.
Is there a way how to improve the insert performance in that case? Use another type of index? Generally avoid indexed RAW columns?
Please help.
Daniel

Hi
After my last tests I conclude at the followings:
The query returns 1-30 records
Test 1: Using Form Builder
- Execution time 7-8 seconds
Test 2: Using Jdeveloper/Toplink/EJB 3.0/ADF and Oracle AS 10.1.3.0
- Execution time 25-27 seconds
Test 3: Using JDBC/ADF and Oracle AS 10.1.3.0
- Execution time 17-18 seconds
When I use:
session.setLogLevel(SessionLog.FINE) and
session.setProfiler(new PerformanceProfiler())
I don’t see any improvement in the execution time of the query.
Thank you
Thanos

Bad query performance - how to analyze it?

Hi all,
since 8 weeks we locate a bad query performance (round about 30% worse than before) in our BW system. At the moment we use a BIA on revision 49 with 4 blades (16GB).
I have already read note 1318214 and analyzed that the most time is spend on the virtual provider(over 80%!).
I´ve seen that a lot of time is spend on the "Datamanager":
For example: It takes 0,76s to select 3.5million items in the relative provider and 78s!!! to select 0 items in the virtual provider.
information from RSDDSTATTREXSERV:
RFC Server BIA client BIA Kernel ABAP RFC
497 464 450 619
So it seems to be a problem an the BW site, what can we do to improve the performance or analyse the query performance better.
Best Regards,
Jens

Hi Jens,
A few checks you may consider doing.
BIA Availability : Check the BI connection with BIA.
Check if you need to rebuild BIA indices again. SAP recommends to do this often, to repair the degenerate indices or delete the indice which are not referenced any more.(eg data in the cube was compressed/deleted and the indices are no more needed.)
Check the if BIA reorganization is required - This is done to see the indices are evenly distribueded areoss the BIA Landscape.
Try to find from BI Admin if major administration work was done within these 8 weeks.eg: Copy cube, dimension restructureing, copying data to some copy cube, archiving etc.
You can use the BIA monitor to peform checks/monitor alerts from BIA servers
[ BIA monitor|http://help.sap.com/saphelp_nw70/helpdata/en/43/7719d270d81a6ee10000000a11466f/content.htm]
This link would tell you on the overall status of the BIA and any actions if required.
Also it has sublinks to other important transaction of BIA monitoring and maintainnance.
To go to BIA monitor : RSA!---> BIA monitor icon.
Is your virtual provider reading data from R/3 or BW.
Generally virtual providers are used to read data from other systems , so it woulfd not have an indices in BIA, I believe if this is the case. except for some applications like BCS wher eyou may be reading data from BW itself.
Hope this helps
Bext regards,
Sunmit.

How can we improve query performance with out indexes?

Hello Experts,
I have a problem with table(calc) which contain 3 crore records and table doesn't have index, on that table one of the view(View_A) created.
When i use the view in below query SELECT count(*)
FROM
Table A INNER JOIN Table B ON (A.a=B.b)
LEFT OUTER JOIN View_A ON ( Table A.a=View_A.a)
LEFT OUTER JOIN View_B ON (Table A.a=View_B.a)
In above query View_A is causing the problem, view_A is created on Calc table. One more thing when i execute select statement on the view it was running fine.
With out View_A query fetching data fine. Update stats of the table also fine. When i run cost plan for scanning only cost % is 90.
Can any help me please?.
Thank you all.
Regards,
Jason.

Jason,
Not sure what you are trying to do. But outer joins are bad for performance. So try to avoid them.
You also say that you have a view on a calc table. What are you calculating? Are you using user defined functions maybe?

Nico

Extremely Slow performance with X58 Platinum

I just upgraded from a core 2 quad 6600 with 8 gb of ram
to a core i7 920 on an X58 Platinum with 12 gb of 1333 ram (yes the ram is an approved spec according to the MSI online manual....I checked the part numbers on the ram)
I have an 9800gx2 and a velociraptor for a system drive, I have all the latest windows updates(vista 64) and the new 1.1 bios revision...and all the graphic card updates and chipset updates from intel
It is running so slow that as I type this the letters on screen cannnot keep up with my fingers, and I am not that fast of a typer.
It fells like I went back in time to a p3 or something.
Where should I begin to diagnose the problem??
Thanks in advance

I too have stepped back in time with my x
MSI x58 platinum board
Specs
Motherboard Name MSI X58 Platinum SLI (MS-7522)Bios 322
3 GIG Ram Aeneon AXH760UD10-16HA08X
CPU Type QuadCore Intel Core i7 920, 3800 MHz (21 x 181)
CPU Cooler Noctua NH-U12P SE1366 LGA1366 i7 Heatpipe Cooler W/ 2XNH-P12 120MM Fan
Hard Drives Raptors SATA Stripe (297 GB)Raid 0
Video nVIDIA GeForce GTX 285 SLI
OS Microsoft Windows Vista Ultimate(64 Bit)
I am running Raid 0 and performance is just terrible.Overclocks like a champ but the board is pretty much useless when it runs slow.
Things I have tried installed BIOS 322 which brang boot time to desktop to 1 minute 45 secs slow but ok I guess,some improvement in a couple games.
Installed XP64 no help or performance gain.
Windows 7 would just not install any drivers at all.
Vista 64 8 installs with no performance with different drivers.(You can install drivers off usb stick)
Bought a new Motherboard but I am going to wait a few days more and see if others BIOS will help.
There seems to be a few new BIOS I will try some them out today.
Contacted MSI tech support and they were kind enough to suggest the bios,you can give that a shot and see if it helps you out.My board is Platinum SLI board but should be same as Platinum board also but they have all the platinum BIos there too.
Regarding your concern,please log into following link to download and update to the latest bios A7522IMS.322:
-ftp link, username, password removed--not for public release
We would suggest you try to update the BIOS by using USB Bootable pendrive.It is convenienct for you:
1.First of all,please make a bootable USB.You can download USBoot.rar from following link.Then please unzip this software and install it to make a booting USB device:
--ftp link, username, password removed--not for public release
2.Next go to our website to download BIOS file, then copy “AFUD4281.exe” and “A7522IMS.322” into USB.
3.After that, restart PC, press F11, choose USB booting under “boot sequence”.
4.Under DOS mode, please type “AFUD4281.exe A7522IMS.322”(without the quotation marks)and it will be updated successfully!!
Remember to clean CMOS and Load Optimized Defaults under bios setup after you finish the BIOS update!
