Revit SWC vs. Save Times

Hi,

 

I'm looking for some advice on this topic but can't find much out on the internet regarding it.

 

We are currently working on a project of ~500 MB in size. We are handling a lot of slowdown on the project as it has grown in size. One of the things that we have noticed is that the SWC can be quite fast but the save either side is giving us issues.

 

E.g. added three walls to the project and synced:

  • 12 seconds for first save
  • 10 seconds for SWC
  • 28 seconds for second save

As you can imagine, this takes much longer with more changes to the model - sometimes 5-10 minutes in total. The more users on the project (up to 8 users) and things can crawl to a stop fairly quickly if a few people try to sync at the same time.

 

I don't fully understand why the save to the desktops is such a slow process - is there a large calculation that occurs with this as well?

 

Could RAM be a factor in this - Revit currently runs at the typical 20x file size (= ~10GB of RAM) and our systems have 16GB total?

 

Any help appreciated.

 

Thanks,

Kevin

Hi Kevin

500mb isn't small to start with and 8 users working simultaneously on the model isn't little (it will be slow) but I do not believe your issue is just RAM related (basic users here do have 32GB min. I myself 512) but it also has to do with the kind of setup you've got...
1. Is it file based or server based colab?
2. All local or WAN based?
3. How is your status with disk space, temp folders ...etc
4. What's in the model (and no it's not the 3-4 new walls causing it to slow down)
5. How often do u maintain the central? Has it been regularly audited?cashed?...

Lots of questions to ask and many probable causes but cheer up 10 seconds isn't thatttt bad : o)

Thanks RDAOU,

 

1. Is it file based or server based colab? Server based
2. All local or WAN based? LAN
3. How is your status with disk space, temp folders ...etc 60-70% free space on local cpu, 30% free space on network
4. What's in the model (and no it's not the 3-4 new walls causing it to slow down) Model contains lots of room families. These are regularly audited to reduce their filesize. Other discipline models are separate as expected.
5. How often do u maintain the central? Has it been regularly audited?cashed?... Central is audited once a month. All local files were cached following upgrade to 2016. Save compact run every 2-4 days. We do have a number of errors in the model but some of these are just the progression of the design, e.g. wall overlaps, that will be removed as the detail progresses. All 'mark' errors have been removed.

 

I'll think about getting the admin to look at additional RAM so - I was mostly surprised that the SWC was quite quick but the saves either side were the real slowdown...I didn't know if it was Revit doing a large regeneration check or something else.

 

Wall creation can be slow as well - normally a 3-5 second wait after each click (blue wheel)!
