    Why my comment got deleted don’t know. But i have tried to make Percona-server-server 5.5.8 pakage from source for my Ubuntu Lucid and the good thing is that this build is really fast as compared to original mysql5.5 build. But will wait for stable release from percona for our website server.

    Has Percona Server implemented MySQL 5.5’s async IO and multiple buffer pools? I seem to remember reading about Percona’s reservation about the effectiveness of those features.

  3. says

    Yes, to both. Async I/O is really important; I don’t think anyone has commented negatively on that, have we? I do not believe that multiple buffer pools are the ultimate solution for scalability (although it is a rather time-honored approach), but it is easy to configure to use a single buffer pool, so I think it’s a win-win to have more options for different situations. I would not be surprised if one of us posts an article here someday showing a case where multiple buffer pools were a really good solution for something particular.

    why remove SHOW PATCHES command?
    and how about adding innodb_check_fragmentation patch to it, i think it is very useful,thanks
