I am trying to build 10.1.26 from mariadb sources and compare the
performance with the release binary for the same query on the same
database.
cmake using -DBUILD_CONFIG=mysql_release resulted in a "jemalloc not
found" error. So, I did a cmake without any parameters and the build
was successful.
The binary which i built has a performance drop of 20-30% for the
queries, compared to that of the released binary, for the same queries.
I compared both the mysqld binaries. The release binary seems to be
accessing jemalloc functions and the mysqld binary which i built do not
have these functions.
I am building this on Centos 6.8.
Any help or pointers will be appreciated
