I just upgraded from 2010 to 2011 and have noticed a considerable performance loss. The files I am working with are large and take a considerable amount of time to open switch between tabs and perform the hatch command. This was not the case with 2010. For information:
I am using Windows 7 64bit
Hardware: I5 core M520 @2.4Ghz, 8gb RAM, ATI FirePro M7820 (have installed the latest drivers)
I have found one way to fix the performance problem, switch to AutoCAD classic instead of the ribbon. I would much rather use the ribbon. There should be a fix for this. I have purged files to try and remove any unwanted information. Little to no help.
Any suggestions are greatly appreciated.
Unless you download and manually install and load VBA for AutoCAD this can't be an issue for a fresh install as ti's no longer installed when AutoCAD is installed.
We noticed a slight performance increase with 2011 and a LOT fewer crashes than 2010.
I using Windows XP PRO 32bit
Hardware: Intel i3 540 Processor, DDR3 1333 2GB, Build-in Graphic
Just Upgraded from Autocad 2007LT to Autocad 2011LT, saving dwg files slow and printing Extremely Slow.
Anyone can help?
Maple - "...considerable amount of time to open switch between tabs..." Try setting LAYERDLGMODE to 0 (old school modal layer manager, I find this metric binloads faster). Kudos to Steve Johnson who tipped me onto that (http://www.blog.cadnauseam.com/). Likely you need to restart Acad to see the effect.
As for "...and perform the hatch command...", I dont think this will help, but pretty sure I saw someone believing that setting HPQUICKPREVIEW to Off helps.
We've switched from ACAD 2007 to 2011 and we are having issues opening files (20+ minutes) and toggling between layouts (long pauses between).
I've turned off the hardware accelerator and seems to have helped the performance once i'm in the drawing, but doesn't help opening.
20 minutes is ridiculous when it would take 30 seconds in ACAD 2007. We've updated and tried different drivers and it seems to have the same performance issues. This is a problem throughout the office and we all have different computer types ect. I wonder if its a network issue that ACAD 2011 is having difficulty with as opposed to 2007(which works great)?
I am also using Windows 7 64bit

This may not be your issue since you're stating your office is having the issue on all different types of computers, but it has made a big difference for us when running ANY version of AutoCAD on a 764 machine.
All Control Panel Items
Network and Sharing Center
Change Adapter Settings
Right-Click "Local Area Connection"
Select the "Advanced" tab
Select the "Speed & Duplex" Property and set the value to "Auto Negotiation"
If it's already set that way, change it to the highest network speed you're network is capable of and see if that fixes your issue. If it does, but the problem reccurs after a reboot, then change it back to "Auto Negotiation".
You should also change the "Power Management" by unchecking the "Allow the computer to turn off this device to save power" (Unless you're running on a laptop). This is a problematic setting on many devices when running under Win7 and the devices seem to not awake and are sluggish after being turned off.
I experience something similar. This week, I switched from my old computer (Core duo, 3 GHz, 3 GB RAM, WinXP x86) to a new one: Core i7-2600, 3.4 GHz, 16 GB RAM, Win7 x64. This is about the fastest you can get now, so I thought AutoCAD 2011 (x64) would be blazing fast. But what a disappointment - all in all it runs quite a bit slower compared to my old machine. For example, switching between open drawings takes quite some time, where the titlebar displays "not responding". It does respond, but very slow. Same for switching between layouts - also takes a lot more time compared to the old machine.
When I check the performance in Task Manager, there's hardly any processor activity and the amount of RAM used is about 15%. Apparantly, there's something else going on, but what?
Search these forums for Speed Up AutoCAD
I've gone through a lot of the discussions on how to 'speed up acad' and have gone through selectionpreview, selectioncycling, hardware acceleration ect. at that point i thought it may have something to do with our network, but that doesn't seem to be the case (one person has a new comp and while he still finds it slow his drawings open up at a reasonable speed... less than a minute). Most in the office are working on older computers and are having a difficult time adjusting to the 10-20 minute wait for a drawing to open. we've updated drivers according to autodesk suggestions, but it doesn't seem to improve the performance. Unfortunately most will not even work in 2011 and prefer 2007 because of the speed. its frustrating because we have to convert and it makes it next to impossible to work when you wait 5, 10, 15 minutes to open files that are in the 1-6 MB range and i feel like our tech person is at a loss because the only solutions autodesk provides is to change the drivers.
i'm curious if other people have had this problem...
do u think moving to 2010 would help?
