Hi,
We're having some performance issues in a specific workflow, where Ruote
will sometimes start going very slow (i.e., 1-2 seconds between messages
with RUOTE_NOISY=true.
Part of the problem seems to be memory consumption (we're running on JRuby
1.7 on top of JDK 7). With this single workflow running, we were running
out of heap space (set to 640M). We upped the heap to 768M and moved
from DefaultHistory to StorageHistory (we're using RuoteMon for storage).
That allowed us to complete the workflow without having an
OutOfMemoryError. However, using JConsole to monitor memory in real time I
see that memory usage will spike to almost all the heap, and then it seems
like the JVM is thrashing, doing a GC (which takes it down to ~500M) and
then filling back up, every 4 seconds.
With the Eclipse Heap Analyzer I've seen that the biggest culprit is the
WaitLogger. The comments in the code say that it stores the last 147
messages for this particular worker, but it isn't clear exactly what it
does and what might happen if we bump that number down.
Another thing that would be useful is to have a description of the columns
that appear in the noisy log. So, for example:
9 00:23.101 20 di * 20121218-1829-jimisuzo-hetsujemo 60311 0_10_1_2
fill_form wi: [0_10_1_2!60311...!, 7], part:
[Abstra::RuoteProject::Participants::PubSubAuthStorageParticipant, {}]
What is the timestamp? The number after it? The abbreviation seems to be
some sort of code specifying which part of the processing is going on (I've
seen ap which I think is something like "accepted", re which I assume is
"reply", di which might mean "dispatch" but there's also rc, dd, re, ce,
la, etc. Then comes the WF name, some hex number, the expid, and a bunch of
parameters. I'd like to know a bit more about this to dig in deeper to see
where exactly the performance problems lie.
Thanks!
-Mario.
