Description:
mysqld on Solaris (Enterprise network binaries) is linked with libmtmalloc, a high performance allocator for threaded applications.  However, libmtmalloc has a high memory overhead, which leads to the server being less efficient than it could be.  Instead of libmtmalloc, the server should be linked with libumem, which also provides better threaded performance than the default allocator, but has a much lower overhead.

How to repeat:
N/A

Suggested fix:
Link with libumem instead of libmtmalloc.
