The project I'm working on is a 190,000 sf high school. There are four of us working simultaneously... Obviously, we're using many worksets... The whole building is in one file.
My workstation is BEEFY and the project is getting unbearably slow. (Dual 3ghz Xeon, 2 gigs of ram, nVidia Quadro FX 1400 graphics card running 2 20" Dell LCDs) Is this still underspec'd?
My question is, what are the things that contribute the most to slowing down / speeding up Revit on large projects?
Could someone please comment on the relative importance of a few potential bottlenecks?
CPU speed, Ram, Video Card, VRAM
Network traffic
Server processor speed, ram, nic speed (gigabit vs megabit)
Does Xref linking (our furniture linework is in autocad) slow things down a lot?
Is it more efficient to explode xrefs into Revit or keep them linked?
Do Model Groups slow things down (grouped linework from ACAD)?
Should I split the project up into pieces?
If so, does the door / room scheduling process get screwed up / more difficult?
ANY HELP WILL BE *****MUCH***** APPRECIATED!!!!!!!

Your linked in AutoCAD furniture file will slow things down tremendously especially if it is from a furniture vendor and they used CAP to place every widget and bolt in the drawing with a bazillion attributes. If you are using worksets, I would make one for the linked in ACAD stuff and not load that workset in my current edition session unless I had too. (note you need to make sure to not open the workset, not just VV it off). In the ACAD world I use Dotsoft's Toolpack to flatten, strip attributes and purge the ACAD file before linking it in as well.
Groups can be a hog as well and if you have ACAD stuff grouped that can be a double whammy.
Be sure that you workset your project in a lgical way that allows you to selectively open only the worksets you require to get your job done. If I'm working on a TI package I probably don't need worksets open that contain structure, site etc. Conversely if I'm working on the exterior shell I probably don't need the interior.
