We've upgraded to Architecture 2009 and are working in a file that fluctuates between 200-300 MB. It's huge and we're preparing to split and link back together. Anyway, it's been slow for a while now. But very recently after upgading 2009, we've begun experiencing an increadible lag when making wall or room edits. 1-2 minutes are required to move a wall or change a room's name. When I look back at what was going on before this started happening, I realize that each time a wall was edited we didn't get this "Regenerating" status in the progress bar. Now each time we make a wall edit the progress bar goes through a few "regenerating" phases in the 1-2 minutes of lock-up/lag/delay. DOES ANYONE HAVE ANY IDEAS THAT MAY EXPLAIN THIS?

I had an issue similar to this, and it was being caused by Norton Antivirus. In my case, as soon as I started using the portable license utlity, Norton Antivirus was doing *something* that slowed the whole thing down. Experienced it on two seperate computers. What antivirus program are you using?

The room calculation is set to area only, therefore, we're not calculating volumes each edit, so that's not the problem unless it's a glitch in 2009 where vol. calc. is always on. Checked w. IT dept. ..no recent change in antivirus software that may have caused this. Edited on: Thu, May 1, 2008 at 3:23:39 PM

There is a good chance it is NOT the antivirus/firewall, but just to clarify I made no changes to Norton prior to the issues arising for me. It was actually once I started using the portable license utility in Revit. The issues had, however resolved with the removal of Norton. It would be worthwhile to rule this out by trying to run Revit with your virus protection and firewall shutoff (with, of course permission and monitoring by your IT staff). As I said, it could very well be something else, but it took me days to get this figured out. Good luck.

Will do Lizard. . Also worth noting, adding casework families, tags, moving doors, etc. is operating @ about the same speed as usual..2-5 sec.delays per operation

The problem persists on a computer w/ no antivirus installed.

to start with, your file is massive and I would think real hard before upgrading to 2009, (and probably wont upgrade) second, do you have lot's of groups in your model? if so, they will slow you down quite a bit, try to eliminate them, also try to avoid grouping lot's of detail lines/components.

As I've mentioned, we know the file is large, and we've suffered through the slowness for a long time. Somtimes 15 seconds to edit a wall if we haven't purged in a while. However, there has been a sudden increase in the amount of time it takes to edit walls and rooms. The upgrade went just fine. We had 2 days after the upgrade of typical (slow) work speed. The third day, however, this phenonmenon started. 1,2 and now 3 minutes to edit a wall or room area. Is what you're saying, Eldados, is that the 2009 upgrade is, in general, too complicated for a file this large? We haven't created a bunch of groups lately either. We're running dual core 3GHz CPU w/ 8GB RAM on XP64 op.syst.

your computer configuration should sufice for a file that size. from past experience, upgrading a large and advance model does not always go as planned, we have a few projects in the office that there is no way I'm going to upgrade. from a recent file I upgraded: after adding a big mass family in order to create some screens as curtail walls (walls by face) Revit 2009 didn't like that at all. had to roll it back... the only thing you can do right now is a process of elimination, trace your steps and see what have changed in the last few days, one by one...

General Causes for Lags in Wall and Room Edits: - You have used join geometry on walls in hundreds of places. Avoid doing this as it adds more calculation time
- You have excessive Errors in your "Review Warning" list. Anything over 400 in a file of that size is bad. Basically, anytime you do anything in Revit it has to check that list to see if any of the errors have been resolved. If you have a lot I'd suggest someone take the time to clean them/resolve as many as possible and you should see some performance improvements.
- You have overlapping room errors, which you'd find in the above process...
- Delete unused rooms, this can only be done from the schedule in 2009, deleting a room from a sheet does not delete the room.
- You have a lot of dimensional constraints on your walls. I generally never lock dimensions of walls, only grids. Do not place constraints in this manner as it causes more harm than good.
These are some of the ones I can think of off the top of head. Let me know if any of these help. Cheers.

Autodesk has said that they won't look at our model until we get our errors down, but the model is too slow to go through them all. I think the problem has to do with room boundaries. Besides errors, what could we do to reduce the room calculations (calc. room vol. is off)? We do link in an exterior model that, now that 2009 can use room boundaries from a linked file, is acting is providing boundaries for all our exterior rooms.

Sounds like your just going to have to invest some time into eliminating errors. Also have you had any luck with turning off worksets to make things go faster?

We've been working with as few worksets turned on as necessary for a long time now. It would seem now that reintegrating the ceiling information was the culprit. Either the pick tool locked too many ceiling sketch lines to walls, or a very few peices of our ceilings, that we have had trouble with in the past, are border-line corrupt. We had formerly kept the ceiling information in a seperate file and linked it in, actually we linked the main file into the ceiling file where we had our RCP sheets. At about the same time that we upgraded to 2009, we brought the ceiling info back into the main central file. We're investigating further.

Sounds like a likely culprit.
