How much data is pushed across the network when doing a STC?

[matt__w]

I posted this over in the MEP group the other day (since that's what I use) but haven't had a response yet. I thought there might be a better chance of getting a response over here so here goes...

Just curious here... how much data is pushed back to the network when performing a save to central? Is it just the few bits or bytes that have changed or is the entire local copy being dumped back or is there something else going on? And how much data is being transferred to constantly monitor who has ownership of what element?

Any info you can proivde will be greatly appreciated!

Thanks in advance!

Pull up Task Manager and watch Networking performance. It will show a percentage
of network utilization.

If you are on a LAN with a gigabit switch and Cat 6 cabling, it should be very fast.

If you are on a WAN, I'm not sure if the Task Mgr. will give a read on the WAN?

cheers......

Cliff, what kind of numbers are you seeing here. I have used Task Manager and Resource Monitor, and never seen more than 60MB/s. Which is really not even saturating a 100MB network. I know from experience that 100MB networks cause problems, and have seen those problems go away as soon as the whole office, or at least team, is on 1000MB. BUT, I can't seem to demonstrate anything like the thru-put I would expect using any network monitoring tool I am familiar with. Makes it a little hard to argue for the expense when your own testing suggests Revit is using all of 6% of the available bandwidth! So I am wondering what kind of bandwidth others see using those tools?

best,
Gordon

I'll leave the high tech talk to Gordon and Cliff. ;)
In lay terms, only changes are saved and synched back to central. I believe this changed in R9.
My understanding or tracking ownership of elements is that it is a relatively minor 'ping' across the network. This may not be absolutely right from a technical standpoint but basically Revit just needs to send notification of user ID and element ID across the network to central file backup folder.

We have a 1 Gigabit network. But then again, our file server is only one. So I'm planning to set-up a Shared drive in a RAID (Stripping) configuration using two hard disk. While waiting for the hard disk to arrive...

This what I do...

I uncheck "Save Local File before and after synchronizing with central" when synchronizing. And select "Save" when saving to local. I feel its faster this way.

Gordon,

We have a gigabit switch, and we see about 20% utilization on STC.

cheers.

My understanding is a normal STC only saves your modifications but before that it reloads other user's changes which often takes more time than writing your changes to central. I recommend reloading before you STC to lessen the possibility of other users getting that file busy key icon warning. Going to a simple view and closing other views speeds it up a little too.

If you compact the central file during STC it will write the whole to the central not just your changes so it usually takes a lot longer and we only do it once a week.

As far as borrowing data constantly being sent it isn't that much but with 5 or more people in the file it can start to lag on even fast networks.
