Yes, I have done it again and now it is fast...perhaps an old version of
svn was slower

I have done some test using a my personal project. It is a set of emacs
library with a lot of small-medium size files

Machine type: AMD Athlon 1600XP
Antivirus Disabled (for optimal test)
4288 files
subversion "version 0.15.0 (r3687)"
Cygwin/bash as shell

Note: the time are VERY VERY approximative. Take them "cum grano salis".
Is it correct the checkout is faster then the export? How can it be?

I have done the export two times for checking if it was an error...

$ time svn cp file:///$SVNREP/truck/emacs file:///$SVNREP/tags/emacsVERSION-1.
0 -m "First Tag Label"

Committed revision 10.

real 0m1.334s
user 0m0.030s
sys 0m0.020s

Total Size of emacsVERSION-1.0: 50732Kb
The output has been redirected to dev null for best performance:
$ time svn export file:///$SVNREP/tags/emacsVERSION-1.0 >/dev/null

real 5m57.648s
user 0m0.010s
sys 0m0.010s

Second time:
real 5m8.661s
user 0m0.020s
sys 0m0.020s

Total Size of emacsVERSION-1.0: 111856Kb
$ time svn co file:///$SVNREP/tags/emacsVERSION-1.0 >/dev/null

real 4m35.756s
user 0m0.020s
sys 0m0.010s
