RE: SVN ( Subversion) in NetApp

I use Netapp NFS and subversion myself in more than one company. I always put the repo on local disk, however, I often do things like benchmark local disk versus netapp NFS performance, and to my amazement, always find that they're comparable. (Sometimes the Netapp is faster, sometimes slower, than the local disk, depending on configuration.)

Here's what I will say about it:

My expectation is that you're seeing a network bottleneck. One (or both) of two possibilities:

 *
I bet the SVN server is taking the files in a network interface from the netapp, and then sending them back out the same network interface to clients. I bet you can completely eliminate the issue by enabling the 2nd network interface of the svn server, and using that interface exclusively to access the netapp. (Depending on your config, this might entail tricky static routes or distinguished subnets).
...
or ...
 *
I bet the svn client is writing files to the same netapp which is serving the files. For example, Netapp --> svn server --> svn client --> Netapp. It would be tough to eliminate this, but it might be possible again, as mentioned, by using a separate subnet or additional network interface.

Hi All,

I have a customer who is running NFS on their SVN (Subversion) server and is having some performance issues. Any documents or best practice docs you may have can help or any previous issues and how you fixed them.

Thanks and regards,

Markus

Subject: SVN( Subversion) in NetApp via NFS performance issue.

Good Day.

We have another performance concern for our Subversion (SVN) server which have a NFS mount in our NetApp filer, before our subversion server storage was in a local disk and after we migrate to NetApp the time to complete for check-out is double already ( for example on local disk it took 7 minutes but in NFS on Netapp it took us around 14-15minutes). Below are the details of the server:

Hardware: Sun Fire(tm) V60
OS: Solaris 10 x86 release 8/7

Apps:
    * Subversion 1.4 - with apache dav support

    * Apache 2.2 - with cdev and corp authentication

Thanks and Best Regards,

Anton
