[JBoss JIRA] (ISPN-5571) CommandAwareRpcDispatcher submits delayed tasks that aren't cancelled if completed before timeout

by William Burns (JIRA)

[ https://issues.jboss.org/browse/ISPN-5571?page=com.atlassian.jira.plugin.... ] William Burns updated ISPN-5571: -------------------------------- Status: Open (was: Pull Request Sent) Git Pull Request: (was: https://github.com/infinispan/infinispan/pull/3559) > CommandAwareRpcDispatcher submits delayed tasks that aren't cancelled if completed before timeout > ------------------------------------------------------------------------------------------------- > > Key: ISPN-5571 > URL: https://issues.jboss.org/browse/ISPN-5571 > Project: Infinispan > Issue Type: Bug > Components: Core > Affects Versions: 8.0.0.Alpha2 > Reporter: William Burns > Assignee: William Burns > Fix For: 8.0.0.Beta1 > > > CommandAwareRpcDispatcher submits async commands to a scheduled executor so that when they time out they are completed. However the task is not removed when the command is completed and thus the task will sit in memory for the duration of the timeout. -- This message was sent by Atlassian JIRA (v6.3.15#6346)

[JBoss JIRA] (ISPN-5542) Shorten interceptor stack for local caches

by Dan Berindei (JIRA)

[ https://issues.jboss.org/browse/ISPN-5542?page=com.atlassian.jira.plugin.... ] Dan Berindei commented on ISPN-5542: ------------------------------------ Ok, so you are only testing read access, and no eviction... the link I posted isn't relevant in this case. The results were a bit lower and more tightly grouped on my machine (i7-4900MQ, OpenJDK 1.8.0_45 with {{-server -XX:+AggressiveOpts -XX:+UseCompressedOops}}): {noformat} Benchmark Mode Cnt Score Error Units MapBenchmark.testCache thrpt 200 11450421.970 ± 64022.513 ops/s MapBenchmark.testChm thrpt 200 121654143.099 ± 349886.912 ops/s MapBenchmark.testDataContainer thrpt 200 96444066.368 ± 1088248.658 ops/s {noformat} Still, it's weird how huge the difference between the CHM and DataContainer results are, considering that all {{DataContainer.get(k)}} does extra is {{if(e != null && e.canExpire())}} and that {{canExpire()}} can be replaced by the JIT with {{false}}. I really expected {{DC.get()}} to be inlined and for DC to perform exactly the same as CHM, but I guess there's still a type guard in there. > Shorten interceptor stack for local caches > ------------------------------------------ > > Key: ISPN-5542 > URL: https://issues.jboss.org/browse/ISPN-5542 > Project: Infinispan > Issue Type: Enhancement > Components: Core > Affects Versions: 8.0.0.Alpha1 > Reporter: Radim Vansa > Assignee: Radim Vansa > Fix For: 8.0.0.Beta1 > > > Accessing local caches is much slower than plain concurrent hash maps, likely due high interceptor stack. One optimization is to have options to remove some interceptors when these are not used. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
