I've got some users reporting slowness on Checkout and Synchronize in
Subclipse. (This is not related to the Subclipse 1.0 release.) Here is
his comment about Synchronizing:
==user comment==
Here are my ball park measurements.
Click on "Synchronize with Repository";
Seems to take about 45 seconds before (what I think is) authentication
to occur (Status label in lower right corner of Eclipse reads
"Synchronizing (0%)")
Synch progress bar pops up.
Takes about another 40-45 sec. to finish (a little less if nothing new
to report).
In addition, anecdotal "evidence" from co-workers seems to correspond
with my experience.
==end user comment==
We're authenicating to an LDAP server thru Apache WebDAV. Apache and
SVN are on the same SUSE Linux box. The CLI is very quick on all
operations so we think this is a problem at the Subclipse level.
Checking out one of our applications is also slow from Subclipse and
takes 11.5 min every time. I've been told it's a large project by SVN
standards - 20046 items, totalling 239.5 MB. It also was brought over
with 4-5 years of history (branches/tags, everything) from CVS using
cvs2svn.
Things we've tried to fix it, nothing worked except #3 and we don't
want to do that:
1) Turning off indexing of the drive on Windows clients
2) Switching the Subclipse preferences to use JavaHL instead of
JavaSVN.
3) Using SSH (we don't really want to lose the LDAP auth, though)
4) Looking through the Subclipse code. I noticed that most of the core
methods in the JavaSVN code (checkout, update) are synchronized. My
theory was that it was the synchronized Java wrapper around the "fast" C
libraries that was slowing things down. But, if this is true, using the
JavaHL setting should have bypassed these methods and made them faster,
which it didn't.
Thanks in advance for any ideas.
Andy
