[infinispan-dev] Staggering remote GET calls

[Radim Vansa]

Only library (embeded) mode, as the load is constant (10 threads issuing requests all the time) I believe that the results are more stable and comparable between runs.

| So you are testing embedded mode with RadarGun?
| Or remotely over hotrod?

| | 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 5.2.0.CR3,
| | or
| | is it the same?

| | 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, but it's
| | actually better :). When I looked on the per-node maximum, in t_825
| | there was only one node with the 219 threads (as the max), others
| | were usually around 25, few around 40. On the contrary, in
| | 5.2.0.CR3
| | all the nodes had maximum around 500!
| | 
| | Glad to bring good news :)

| | | 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 working on that with Bela),
| | | but reducing pressure on the OOB thread pool is a side effect of
| | | this fix.
| | | 
| | | It should generally make things faster too, with less traffic on
| | | the
| | | network. I'd be curious for you to give this branch a try, Radim
| | | -
| | | see how it impacts your tests.
