WL#4965: Change default of InnoDB Thread Concurrency to 0
Affects: Server-5.4 — Status: Complete — Priority: Medium
Changed default of InnoDB Thread Concurrency to 0. In MySQL 5.4.0
In MySQL 5.4.0, change the default of innodb_thread_concurrency from 8 to 0. In effect, this changes concurrency from 8 to “infinite”. This change is made to provide better “out of box” configuration of default values for MySQL operation on up to 16-way x86 servers and 64-way CMT servers with 4GB or more memory.
Default value of an existing variable changed; no further LLD required.
