Maven Performance
Hi
We are using Maven2 - Archiva and last two weeks we have serious
performance problems. Maven is taking more than 15min to build
relatively small project. Apparently the problem is getting updates
from one of the 4 Archiva repositories.
What could the cause of this? Could it be a Maven's local
configuration problem ?
BTW. Archiva is generating tons of WARN messages: Resource does
not exist: Unable to locate resource in repository?!? and File does
not exist exception.
Angel.

here is the message I'm getting from Archiva :

this message repeats literally thousands of times. The info presented
is not enough and i can't find what is causing it.
Maven in the mean time waits:

I've set everything local on the server there are no shares or remote
resources.
all repositories resides on separate hard drive and there in more than
300GB space
/dev/hde2 350G 32G 319G 19% /workspace
$ls -l /workspace/mavenrepos/
total 6

Nope the server is in perfect condition. The load is 0.07 while
Archiva is running so there are plenty of resources available to
Archiva, i've even tried changing the nice so that is can be almost
real time scheduled

Yes everything is up to date
dev-java/maven-bin-2.0.7
dev-java/sun-jdk-1.5.0.13
i've build Archiva manually there was some null pointer exception that
needed to be fixed.
archiva-1.0-beta3

My guess would be that this is some kind of proxy-repository
misconfiguration or mistake, but the documentation is exiguous and
cant' find anything on the net. I've also installed couple previous
versions of archiva with no success.
i still can't find neat solution to the CHECKSUM PROBLEM
[WARNING] *** CHECKSUM FAILED - Error retrieving checksum file for
org/richfaces/suggestionbox/3.0.2-SNAPSHOT/maven-metadata.xml - IGNORING
[INFO] snapshot org.richfaces:suggestionbox:3.0.2-SNAPSHOT: checking

could this be the main reason for lag?

If a build has to plow through these messages for every file access, I'd
think that would slow things down. Can you zero in on these error
messages? Are there server messages in logs that can help you?
Resource does not exist: if the file is on a network share, has it been
moved? Has the share of nfs file system been unmounted? A reboot of a
server with a non-permanent mount could cause this. Did someone do
maintenance on your server without telling you? Example, Gee I need to
find some disc space. Angel hasn't updated this file in 3 months. I'll
delete it to make room for my stuff.
If your server is running smart disk utilities, is your hard drive
causing problems? A bad disk may cause these messages i.e. a disk may
be ready to fail. A missing file or directory, can be your first hint of
a coming failure http://www.linuxjournal.com/article/6983 .
Did you install a new version of Maven, Jdk, archiva, plugin, etc?

You'd need to proved this kind of information too. At this point I can
only provide wild guesses to get you started on a solution. It would be
interesting to hear what you found in a follow-up email.
