This is why I love this list, something comes out of the blue you didn't
know you need but turns out to be useful!
For anyone interested, I just tried this on a repo I had handy: 1.5Gb on
disk with 1189 revs and got these results:
| Before pack | After pack |
-----------|---------------|---------------|
Files | 12 | 12 |
Folders | 2,406 | 1,408 |
File Size | 1,597,121,193 | 1,597,132,101 |
Disk Size | 1,604,366,336 | 1,602,351,104 |
============================================
This is on a windoze XP system using NTFS. Packing took ~four minutes:
D:\svn\test>date /t && time /t && svnadmin pack test.svn && time /t
27/05/2010
08:02
Packing shard 0...done.
08:07
D:\svn\test>svnadmin --version
svnadmin, version 1.6.11 (r934486)
compiled Apr 18 2010, 23:12:22
Finally, as noted elsewhere, this is using v1.6 pack which does not pack
revprops (hence only 1/2 files packed) but 1.7 should pack those as
well...
