perhaps the real solution to the performance issue you mention is to have svnadmin actually write to a target file instead of crossing process boundaries to redirect stdout ?

have you tried :

Start-Process '{PATHTOSUBVERSION}\svnadmin' -argumentlist "dump {PATH_TO_REPOSITORY}" -RedirectStandardOutput c:\temp\repodump.dmp -Wait

Never tried that. I will have a go. Thanks for the suggestion.

Unfortunately its very verbose for a simple case which works fine in cmd so I'm not sure that it warrants using that tool
