Re: Java databases as alternative to MySQL on OS X Server?




I doubt that you will find any database that is faster, and still free, other than MySQL. MySQL performs excellent with SELECT statements.
I may be wrong, but from what I have seen I can't see any JVM based DB outperforming MySQL.


OT:
I have been looking at OSX performance problems since OSX 10 beta days, and it is abysmal in many low level areas.
The article writer stumbled on just a few of those and, maybe too hastily, blamed it all on one bottleneck.


The bottom line is that the real world performance of Apache and MySQL is really lacking on OSX, and the hardware is not to blame.
It was a positive review of Apple hardware, and it publicized some of Darwin issues present from the day 1.
(Note how many good performance stories of OSX are about DSP-style processing, and none about highly fragmented processing)


I just hope for more cool-headed public discussions on Darwin performance problems, as OSX would fare so much better with better Darwin.

And I didn't think they wrote good science fiction anymore.
This article appears to note performance differences for MySQL between OS/X and Linux running on the same or similar hardware. After completely failing to come up with anything to explain the differences it then wildly speculates that it is because of threading. Part of the basis for this was that a paragraph in the documentation for MySQL says threading is important to performance. I'm not remembering that any more conclusive proof was provided.
I think the whole article took a improper approach. It says MySQL performance has issues and then attempts to reach a conclusion that OS/X threading is a performance concern. More correct would of been to try and prove that threads are in fact sometimes a performance issue and then try and connect that to specific domains like MySQL performance.
