OK, I think we found the “problem”. I use my Blog to present my Smilies and I added each Smilie to the wpsmiliestrans-array in functions.php. So the array has 1.800 lines. 😀
If I remove all Smilies from the array, the load goes done significantly!
But, as you can see in my cpu load graph:
http://www.greensmilies.com/wp-content/uploads/2008/01/cpu-day19-22.png
the load without the large array is much higher than under 2.0.11 with the large array!
Why it was better under 2.0.11?
Any ideas, what I can do? I don’t wanna remove the smilies, because they are the topic of my blog and I used them in hundreds of topics…
My Server-Admin also said me, that a lexer is faster than a parser and WP should use it… just his 2 cents.
For examlpe: http://greg.chiaraquartet.net/archives/138-PHP_ParserGenerator-and-PHP_LexerGenerator.html
Thanks for reading! 🙂
/edit:
I use a dedicated server with an AMD Athlon(tm) 64 X2 Dual Core Processor 4600+ (2400 mhz) and 2 gigs of ram.

Nobody?
🙁
Here are some more cpu load statistics. The show WP 2.0.11, WP 2.3.2 and WP 2.3.2 with the Wp Super Cache Plugin:

Same traffic and smiley array as under WP 2.0.11, will explode the load under WP 2.3.2. Super Cache did a good job but 2.0.11 was better…

k, still no reply, continuing one-on-one interview. 😀
As I wrote above, I extended the wpsmiliestrans-array in functions.php up to 1.800 lines. Since I removed all Smilies from this array and replaced them with only 20 Smilies, the cpu load goes down. I also use WP Super Cache now.
The load goes down, but is still higher than under 2.0.11, I hope, it will be better under 2.5
