Made 2 tests...
installed everything on a second machine
AMD Duron 800MB single CPU, 256MB Ram, Suse Linux 8.2
Kernel 2.4.20
apache2 2.0.47
berkley 4.1.25
subversion 0.30.0
And here it works... I did the cycle 5 times... But it is slow. Checking in
of apache 2.0.47
(all local on the same machine, but using http - as shown in my initial
mail) takes about 8 minutes
Only small disk activity, no swapping, CPU ~90% idle (from what top says)
during checkin
(the phase where dots are painted, I think each for a file) before and
afterwards there are phases which
much higher load. Moderate memory consumtion of svn/httpd processes (6-17
MB)
Afterwards I went back to my 2 cpu machine and recompiled everything with
berkeley 4.0.14
Then checkin works.... Slow but it works. So I assume that Ray is right,
that this might be an
issue of BDB 4.1.25 with 2 CPUs. From what I have seen at sleepycat.com
(and the dev mailinglist)
there is a version 4.2.xx scheduled for october with changes in locking
code. Maybe this
helps subversion (and me). I am also eager to get subversion 0.31.0 where
issue 1490 and 1499 appaer
to be fixed (from what I have seen in the branches area of svn.collab.net).
Maybe this helps here to.
On weekend I will disable one cpu on my dual machine and make again a test
with BDB 4.1.25
(and a run with memtest86)
