Well my results are 'interesting'. Like Edward my on disk size for SVN is
288MB and CVS is 96MB -- this is on WinXP. I put a network snooper (ethereal)
on while doing a full checkout and the results are a bit odd:

           Packets Bytes Time (minutes)
TurtleSVN 21,846 19,608,899 ~6
WinCVS 77,184 69,223,709 ~4.5

I don't have an explanation for the results other than the possibility the in
fact there is more compression with TurtleSVN. Frankly I'm dubious about the
measurements except the part where SVN was 1.5 minutes slower...

Otherwise, TurtleSVN seems easy to use and does a nice job. I was able to
modify a file, do a check-in, see the log changes. For basic 'head-based'
development it seems like the learning time was very small. I really like the
SVN URL approach for the repository path. This is so much easier to
understand the the CVS root :pserver:blah_blah_blah stuff (I had to spend 5
minutes remembering how to do that again with WinCVS).

One problem I encounted was an error when I tried to run a 'revision graph' on
a file. The file is:


The error is:

REPORT request failed on /boost/!svn/bc/19699
The REPORT request returned invalid XML in the response: XML parse error at
the line 203135:not well-formed (invalid token)(/boost/!svn/bc/19699)

Not sure if this is a TortoiseSVN problem or something about the repository setup.


ps: Double thx to Troy for setting this up -- it has been very helpful!
