I\'m using TortoiseSVN on my development machine (running Windows Server 2003) and VisualSVN Server on the server side. Both are the latest versions (against Subversion 1.6.5).<
By far the biggest performance increase I got was to set the client's Icon Overlays to not process the whole hard drive, only the locations my SVN files live in.
To do this, open the settings (right-click in Explorer->TortoiseSVN->Settings), select Icon Overlays, then in the Exclude paths: enter c:\*
In the Include paths: enter the paths to your Subversion working copy directories (for me all are under c:\subversion\*
and c:\workspaces\*
)
Use a newline to separate entries (see screenshot)
This made the client seem a thousand times quicker.
This screenshot shows how to exclude c: and d: drives, just including the relevant directories:
You can get some more performance tips from the TortoiseSVN docs.
