Speed Problem
Hi all!
I am using subversion "version 0.15.0 (r3687)"
It works well but it is very slow
I am using a local repository (no http/webdav)
with 4288 files on a standard pc.
It tooks some minutes do do an export or a checkout.
Also the cp commands (for tagging) are very slow!!
What is the reason?
I am using the cygwin as shell.
Some suggestion?
Keep going on!
I like subversion!!!

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
WindowsXP
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...
CP:
$ 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
EXPORT:
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
CHECKOUT:
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

cp slow??
Incredibly fast for me on a Suse 8.0 & Athlon 950.
The import is slow, but I wasn't going to compain yet.
This is alpha stuff, and I'd prefer to see it not mangle repository or
segfault rather than import in the blink of an eye.

Oh, well sure, you *could* do it that way, but then how would I look
like an idiot? ;)

Yeah, that's more likely what I did, not realizing the above was an
option :)
Thanks for the clueX4, I'll go beat myself with it now :)

It may look like I'm just sitting here doing nothing,
but I'm really actively waiting for all my problems to go away.
If you're not having fun, you're not doing it right!

'svn cp URL URL' should be contant time, extremely fast. It's
currently seeming that way, because mod_dav_svn is erroneously sending
a full walk of the copied tree back to the client. There's an issue
filed on this.
'svn cp wc wc' -- well, it's a heck of a lot of copying. That really
is an O(N) operation.

I noticed the same thing under Debian doing a cp on the wc using
ra_local as well, fwiw. My repo was the linux 2.4.19 kernel tree
and took an unbearably long time to finish.
I'll be glad to run some tests on this if you'd like, just tell me
what type of info you're looking for.
