Sorry, but this is just plain wrong. The actual article does a better time explaining and disclosing this small, specific speedup. MySQL InnoDB in 5.4 is faster on >4 multicore servers because it properly accounts for the extra CPUs. Calling it a "60% performance gain" is really misleading.
> One of the primary fixes in MySQL 5.4 is that the InnoDB storage engine can now address more than 4 CPU's/cores
- amix 18y agoYou are correct, it's mostly targeted at multicore servers and the preview only holds Google's InnoDB patches. Generally thought, I hope they keep looking at performance issues beyond the InnoDB mutex patches - - and set some of the Sun optimization wizards to optimize MySQL. Sun has some _very_ bright people (those that have made ZFS, DTrace, Solaris, Java's VM etc.) that could optimize MySQL to new levels. Let's just hope they don't drown in bureaucracy.
