According to the benchmarks on the Personal website, the 5.1 version of Persona has the same about performance as mysql 5.5 (http://www.percona.com/software/benchmarks/) Also the 5.5 version of the Persona(not reported as stable) is even better than mysql 5.5 according the the same site.
Also after reading Dimitrik blog (http://dimitrik.free.fr/blog/archives/2010/07/mysql-performance-innodb-io-capacity-flushing.html), its seems to me , than one of the thing that are different between the stock mysql (5.5) and xtradb, is the way that they handle IO capacity and flush. So if you need to control the IO then you should use the stock mysql. My opinion is that both servers(personal 5.1 - mysql 5.5) , seem to be good enough for extreme workloads and they will do your job. Also (if it's an option) you can install both , and test them with a synthetic benchmark like sysbench. akops On 14/2/2011 4:34 μμ, Jay Ess wrote: > On 2011-02-14 15:31, Singer X.J.
