Subject [jira] [Commented] (CASSANDRA-9197) Startup slowdown due to preloading jemalloc
Date Thu, 16 Apr 2015 18:21:03 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9197?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14498447#comment-14498447
] 

Robert Stupp commented on CASSANDRA-9197:
-----------------------------------------

jemalloc affects all allocations (including all off-heap allocations)

It might be possible that the shell script code in {{conf/cassandra-env.sh}} gets slower since
the {{find_library}} might be a bit inefficient. [~philipthompson] can you try to let {{conf/cassandra-env.sh}}
skip the "find the jemalloc lib" code and hard-code {{CASSANDRA_LIBJEMALLOC}} and see if that
mitigates the problem?

> On my box, it seems that the jemalloc loading from CASSANDRA-8714 made the process take
~10 seconds to even start (I have no explication for it). I don't know if it's specific to
my machine or not, so that ticket is mainly so someone else can check if it sees the same,
in particular for jenkins. If it does sees the same slowness, we might want to at least disable
jemalloc for dtests.
