Subversion fitness

Setup

TCK was run in two different setups:

• on an unversioned filesystem
• on a versioned filesystem, all files with svn status uptodate

Result

After running the TCK set various places causing massive file access were identified and fixed in the subversion and versioning modules.

The following tables summarize measured file access before and after fixing the relevant VCS modules. Please note that all values are an average from multiple runs

Unversioned files

• Before fix

Type	Overall file access	File access from svn
Read	11919	3921

Delete	182	0

Overall file access - includes all involved parties - TCK, subversion, versioning, whatever else ...
