We've seen a significant increase in time it takes to download/upload artifacts from Archiva after we upgraded from 1.2.2 to 1.3. I'm in the very beginning stages of my investigation, but one thing I just noticed when comparing the Archiva WAR between 1.2.2 and 1.3 is that the plexus-cache-ehcache-1.0-alpha-2.jar in the 1.3 release says it was built March 29, 2007 by Brett...and the version in 1.2.2 was build Jun 23 2009 by Deng. If you JAD the EhcacheCreator classes between the two, there are some fairly significant differences between the them. I'm not suggesting that this has anything to do with our issues, but I wanted to point it out as a can't imagine that you intentionally moved back to a version of ehcache that was two years older than the one you included in the 1.2.2 release.
