[wp-hackers] 5 minutes to a faster blog

I tried to increase performance, too ... and found out the following things:
- eAccelerator (and any other PHP-Accelerator) increaseed performance 2x
often 3x (depending on the script that runs, frontpage = 2x)
- enabling the mysql query cache helped a lot, but only if the $now in
the posts-query gets frozen
otherwise the frontpage doesn't benefit too much from it
- switching to innodb actually decreased performance (nearly not
measureable) on my install, but maybe my blog is too small with its 1500
- enabling the built in cache decreased performance by 10%. So I guess
my HD is simply too slow :-)
hdparm -tT /dev/md0
Timing cached reads: 1908 MB in 2.00 seconds = 953.94 MB/sec
Timing buffered disk reads: 146 MB in 3.02 seconds = 48.28 MB/sec
- deactivating the gzip compression in the wp options panel increased
performance a little bit
- activating wp-cache (the plugin) increased performance by a factor of
6 (on my blog from 5 request per second to 30 request per second)
Did I forget anything?
