Svn Server Scaling

• Use a reliable replicated nfs server (NAS appliance?)

• Use multiple svn server frontends: 2-4

• Turn off atime updates (relatime on recent linux)

• atime may need to be disabled on nfs server (not client)

• Switch to sharded revisions in svn 1.5

• Make sure your fsync() are fast (raid/memory fronted drives/ack nfs early)

• Transactions can be built (write intensive) on local disk before being promoted to a revision on nfs
