Guys,
I have a topic branch with a fix for ISPN-825, to stagger remote GET calls.
(See the JIRA for details on this patch).
This should have an interesting effect on greatly reducing the pressure on the
OOB thread pool. This isn't a *real* fix for the problem that Radim reported
(Pedro is wo
Hi Manik,
so I have tried to compile this branch and issued a 20 minute stress test
(preceded by 10 minute warmup) on 128 nodes, where each node has 10 stressor
threads.
While in 5.2.0.CR3 the maximum OOB threadpool size was 553 with this
configuration, with t_825 it was 219. This looks good, b
Radim, just to be sure, you are testing embedded mode with RadarGun, right?
With HotRod most of the get operations should be initiated from the main
owner, so Manik's changes shouldn't make a big difference in the number of
active threads.
How about throughput, has it also improved compared to 5.2

Thanks. As Dan suggested, the staggering of requests should ONLY have an

Excellent !

Awesome. :) Mircea, are you going to finish up my patch, make the staggering
timeout configurable, etc?

Manik, as I have stated in later mails, the test was not executed properly,
therefore these good results.
Actually, I think there is a bug in the branch, as you set expected responses
in FutureCollator to dest.size() but still send only one message, if the first
response is not successful but wi

+1. Also the performance increase
Tune in real-time, of course ;)
