Hi, We are using Revit 9.1Our machines have 2GB of RAMOur file size is 75MB Both Arch & Structural Models are in the one file using a good number of worksets.We have up to 6 people working on the model at one time.We are have a lot of problems with stability and speed when "Saving to Central" Saving can take up to 20 minutes, up to 10 just to reload latest on opening the model.Surely this is not normal? And fatal errors are a daily occurrence. Can anyone suggest any quick fixes or recommended procedures or solutions to improve performance & save time? Also if you could give me an idea of how long saving to central should take under the correct circumstances, I know this varies depending on the work done. But a rough idea would do. Any help would be great! Thanks!

Wow! We think it's slow when our current 90 meg project takes more than 5-6 minutes. This 90 meg project has 3 options in it and is linked to a site that has about 6 options in it and we are not having any problems managing these links. We have worksets enabled but we have not really broken the project up into seperate worksets - just using the default worksets that REVIT creates. We are thinking that we will need to better use worksets on larger projects but so far, we have not had to. Note that the help says that "Performance is improved if added worksets are not visible by default." We have not yet found an engineer using REVIT so I can't really address that aspect but I'm surprised you did not split the structural out and just link the two portions of the project.

We didn't split the Arch & Structural into 2 files as we were under the impression it would not cause problems. Could this be the problem is a 75MB file to large?

If the model contains both Arch and Struct data, how do you Copy/Monitor the model for changes. I thought the whole point of having Arch and Struct models was so that Revit could monitor changes and interferances. I haven't actually gotten to work with a Structural model yet, so this is just my understanding. What is your network speed like. Are you using 10/100 eithernet connection or the newer 10/100/1000 connection? We saw a great decrease in our "Save to Central" times when we upgraded to a Gigabit connection (10/100/1000). For this to work you will need the server, the router/switch, and each Revit workstation to use the newer connection (10/100/1000). It does seem like a long time to wait for a save that really isn't that big. You might consider breaking the Structual out just to save time. Maybe also try to Purge Unsued... Though the size probably isn't the real problem. Good luck

We found ours was taking up to 35-40 minutes to save to central with Revit structure 4. The biggest problem was having so many people (4) on the same file (central) at the same time. If you save frequently it will save you time on your saves. Plus if you separate the arch and struct. model that should split the number of people on the each, again increasing your time. I would maybe think about doing the arch as it's own central. Struct as it's own central, and then have another with the two combined. (possibly 3 centrals total.) Or just "link" the others file into the respective disiplines and each be responsable for their own construction documents. Just a thought! HTH JB

Yes in future we will definately have 2 central files. one for each discipline. As for the copy monitor facility i'm not familiar with this so i don't know if that would be the main reason to split a model. my understanding is that we have a 100mb connection to the server. the details of this i'm not sure, just what my IT guy told me Does anyone know how easy it would be to split the two model out after the bulk of the work has been modelled? i had a quick look at doing this and when trying to separate them i got a lot of errors to do with joined & constrained elements. If i ignored these errors would it mess up a lot of things?

Though I've never had to so it, I would probably copy the central file to another location and then start deleting either Structural or Arch. Then on the other I would start deleting the opposite. NOTE: I would make an original backup before I start doing anything!!!! Thats just what I would do. HTH JB

yes, that is probably how to do it. would rather not have to. thanks for everyones imput. I'm really suprised that Revit is this counter productive with regard to time spent waiting on saves

It seems to me even around my office here, that there's some people who are ready to throw Revit under the bus because of this. You do have to remember what exactly it is that Revit is doing when it takes so long. It's checking eveerything that you've moved/changed and comparing it to everything everyone (6 people in your case) else has moved/changed. That's pretty sofisticated. Besides, the fact that multiple people can even work on the same file at the same time is revolutionary!!!!! My thoughts, not yours! JB

A really helpful way to speed up saving is to do this. Make a drafting view and call it something like "Save To Central". Then every time you need to save to central go to that drafting view hit XX to close all hidden windows. Then save to central. If you are still having issues when trying that then make sure that you have only the worksets your working on opened, and you may still want to seperate into two seperate central files (I dont know who gave you the impression that it wouldnt cause any issues to have it in one). Get 4 gigs of ram and put a 3gig switch onto your XP os. After all that if it still takes for ever to save to central then you should do: Go to drafting view "Save to Central"...Close hidden windows...Save Localy...Reload Latest...Save to Central you can actually pick up a bit of time doing this as well, but first just try the things listed above.

Tips to Reduce 'Save to Central' time Open selective worksets instead of the full model. (see below) 
Close any hidden windows before saving to central. When away from your desk for any considerable amount of time close out of the model completely. Save locally first & reload latest before saving to central. Save often to reduce the risk of instability issues. Reboot/Shutdown machine each evening. Please add to this if you have any other tips! thanks everyone
