Hi, sure, I'll get a few this evening. And to note: Not the whole system is slow, just uploads via Maven from our Jenkins.
Searches in the UI are "normal", also builds / downloads don't seem to be particularly slow. Maybe Jackrabbit does some cleanup jobs during the night / once a day? A colleague which works on a project also using Jackrabbit as datastore said something that there are very small index files which eventually get merged to some bigger index. Could that be it? I think our SAN behaves particularly bad when a lot of small files are involved. Anyway, I just counted the files in the index directory and took the first 10 thread dumps. Will do the same later Greetings -Sascha- Am 20.05.2014 01:52, schrieb Olivier Lamy: > Hi, > Really hard to know exactly what happen. > Do you have time to get a jstack while the system is slow? > > Olivier > > On 15 May 2014 18:24, Sascha Vogt <[email protected]> wrote: >> Hi all, >> >> we're experiencing a strange behavior in our Archiva instance (latest >> 2.1.0-SNAPSHOT): >> >> During the day, the upload performance from Jenkins degrades heavily.
