- This was done to get better performance when doing a lot of connections. Ensure that thread_cache_size is not larger than max_connections (trivial optimizations). Fixed that the --host_cache_size=# startup option works mysql-test/r/variables.result: Increase back_log to 150 sql/hostname.cc: Fixed that the --host_cache_size=# startup option works sql/mysqld.cc: Ensure that back_log and thread_cache_size is not set higher than max_connections (as this would not make any sense). sql/sys_vars.cc: Increased back_log to 150
