Re: Large Commit Issues! 10Mbps Upload cap on a Gigabit LAN

specifically for the client (if applicable thn server too) .. look 4 and disable following
a) anti-virus (or exclude SVN working copies)
b) desktop search tools -- e.g. GDS, MSNSearch etc.
c) Any indexing service (MS Indexing)

yeah, perfmon will be a way to look as u state its a Win32 client/server.

without actual confirg details, its difficult to help, for you say you have already looked at everything!

regards

  Probably a disk IO issue, on your Win2K3 server can you run the perfmon tool
  (Start->Administratiion Tools -> Peformance) when you do the co/ci and tell us
  what you see under view report for -

  Memory pages/s
  Physical disk, Avg Disk Q length

  While you are at it, you may want to fill in the info Samay requested in the last email.

  When you say "any other tranfer" is > 450 Mbps, what kind of transfer is that ? I mean SVN
  will need to create the transaction file when ci'ing and unless you have super fast disk (Ultra 320
  SCSI etc) writing at sustained 450 Mbps is unlikely. The 10 Mbps disk IO on commit on the other hand
  is also low unless you have very slow disks. What's the disk specs like ? The other apps may be reading
  buffer cache and not going to physical disk at all so that caveat applies, but after a checkout buffer
  cache should be warm and you should see faster transfer for checkouts.

    Thanks for getting back to me.  But I've looked at every other possible bottle neck.  Anyother transfer from the server to client is blazing fast (at least 450+Mbps).  I had it down to just the PC & server talking, and there is no way I could get a checkout done where more than 20Mbps bandwidth use (I was checking the bandwidth usage as soon as I did a checkout or checkin).  I'm pretty sure it's subversion itself, doing some sort of memory stuff, where a buffer size is set or something...  Both my PC & Server are running on Window (PC: XP SP2 Server: Win'03).  It's just wierd!  It takes me a long time (>50mins) to do a ~5-10GB checkin/checkout.  That's just waaay too slow when I have nearly a TerraByte worth of data that I need to put under version control.  I read some other people were having similar issues with checkin/checkout of large files, I mean 10-20Mbps is great, just not so great on where you have a 1Gb connection with no bottlenecks.  Once again, thanks for any input on this matter.  I am a passionate advocate for open-source software, and if I would love to put show off a subversion system to some of the microsoft groupie execs, so please help!

      Transfer speed also depends on 
      a) server specs -> processor, memory
      b) bus speed
      c) any IRQ sharing (e.g. Eth0 & Drive Controller sharing same IRQ-- ouch!!)
      d) speed of drives & raid controller, raid config
      e) server load (processes in wait stage?)
      f) operating system & configuration.
      g) and MTU (jumbo frames?) on the network itself 
      of course least common denominator of the server & cliebt capability defines the over all speed u may get. Care to share details above?

        Subject: Large Commit Issues! 10Mbps Upload cap on a Gigabit LAN
         
          Hi, I'm running into an issue that nobody seems to know a heck of  a lot about.  I'm moving a whole bunch of files from an old repository system (RCS) to SVN (i.e 80,000+ files, ~60GB).  However, checking in is virtually impossible.   I have a Gigabit connection to the server and all other data transfers are blazing fast except for SVN which caps at 10Mbps uploading to the server and 20Mbps when I'm checking out.  I would really, really appreciate any help on this subject as I have googled this for hours to no avail. 
          Thanks,
          Ahmed
