XtraDB scalability

 Recently I discovered a new storage engine for MySQL called XtraDB. Since Oracle's acquisition of InnoDB MySQL is trying to find a substitute, but so far nothing has come close to its maturity and stability.

XtraDB is basically a InnoDB fork focused on scalability. What's so special about that ? Well their preliminary patches and benchmarks are exactly centered around locks. Most patches actually come from google-mysql-tools.

During a benchmark session on a 24-core machine the XtraDB team discovered a concurrency problem on the rollback segment.
