File sizes somewhere between 300MB and 1GB 2.5.6 begins
having noticeable issues.  This is not a limit but merely
pushing the capacity of truncated digests. This problem
impacts performance only. It can be mitigated somewhat by
using a larger block size.  These issues have been fixed in
CVS so 2.5.7 and later will be fine with huge files.

There is no hard limit on file count you could hit.
Each file requires approximately 70 + path-length bytes so it
is a question of how much process addressable memory you have.
