Hello Bradley,
I just ran a simple test that checks out JavaSVN's trunk over svn+ssh, on my
computer JavaSVN works faster comparing to command client:
checkout.jsvn: 53813 ms.
checkout.cli: 89360 ms.
(on Windows XP, JDK 1.5.0_06).
So, main suspect for me is symbolic links resolution that indeed could
introduce significant overhead on JavaSVN operations, as Java doesn't
support symbolic links and JavaSVN has to execute native programs to resove
symbolic links. In certain cases it do that for every file in the working
copy, probably that could be your case. I do not think that Ganymed library
is what causes slowdown, at least it less probable.
I will send you a version of JavaSVN with hardcoded disabled symbolic links
support, please try using it. Put the library into
ECLIPSE_HOME/plugings/SUBCLIPSE_CORE_PLUGIN/lib directory (instead of
existing javasvn.jar) and restart Eclipse with -clean option. Before running
a checkout please make sure that JavaSVN is selected as a client adapter in
Eclipse SVN preferences.
In case this version of JavaSVN will not resolve the problem, please enable
debug logging for JavaSVN, put the following in your
JDK_HOME/jre/lib/logging.properties file:
handlers= java.util.logging.FileHandler
.level= FINEST
java.util.logging.FileHandler.pattern = %h/java%u.log
java.util.logging.FileHandler.limit = 0
java.util.logging.FileHandler.count = 1
java.util.logging.FileHandler.formatter = java.util.logging.SimpleFormatter
Then rerun checkout and send me ~/java0.log file. Thanks!
