SVN checkout is extremely slow from Bamboo after upgrading from 5.1.0 to 5.6.2.

Manually performing an SVN checkout on the same server takes about 5 minutes to check out 1.3GB of code but Bamboo is taking a long time to perform the same checkout:

• Checkout time using svnkit 1.7.13: 4:20
• Checkout time using svnkit 1.8.6: 8:35
• Checkout time using native client: 1:45
• Checkout time using Bamboo: 55:42

The SVN server is CollabNet Subversion 1.7.9
The SVN client installed on the build server is CollabNet 1.7.11

This has proved to be a bug in the third-party SVNKit library: http://issues.tmatesoft.com/issue/SVNKIT-553

Some tweaks that might help:

• Using SVN Export
• Setting the working copy format to 1.6 (Navigate to: Administration > Repository settings > Subversion (tab))
