Your question would be more appropriate on mysql list. However here's some comments from me: - select count(*) is NOT a suitable query for performance measurement. Short version: some storage engines cheat, they don't exactly do the count, only returns the estimate. - if you read http://www.paralleluniverse-inc.com/parallel_universe_5.5-3.1_usage_guide.txt , you'll see that only certain kinds of queries will benefit from their tech, and even then you must explicitly set some variables - for generic use on a single server, I currently use tokudb (on some server) and mariadb with tokudb engine (on some others). I'm happy with the results so far -- Fajar _______________________________________________ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users
