Re: Lots of files

Nicklas,

    Here are my thoughts about a couple of things to consider:

> Norton AV is enabled and scans all accesses and all files.

    If you have modern AV tools and are guarding most of the entry points to
your computer, it's pretty unlikely for a virus to crop up in a work area,
unless there are many MS Office documents in it. I exclude my work areas
from our AV scans.

> Network access is pretty much unloaded 100 Mb/s.

    With such bandwidth, you won't hit some of CVS's performance limitations
over small pipes, like VPN connections. Is off-site development relevant? If
so, try some of those tests.

> Over 200 MB wasted space

    Some quick calculations with your numbers suggest that you have a 2048
byte block size on your disk, which means the small administrative files
maintained by both CVS and SVN are taking up much more space on disk than
their internal bytes account for. If you have good reasons for going with
such a large block size (up from the 512 default of NTFS), you should
generally write off the extra "on disk" space as a time-space trade-off and
not penalize tools that maintain small files.

    Finally, I have found that the time taken to run an "svn up" the first
time is much longer than running it a second time, because all those tiny
administrative files get cached in the file system's cache. Did your times
represent the first or second time?
