I use many plugins, but to test it, I disabled all plugins and I still have a high cpu load. * Here you can see the different between 2.0.11 and 2.3.2, I updated one 1 o’clock: [http://www.greensmilies.com/wp-content/uploads/2008/01/080120_cpu.png](http://www.greensmilies.com/wp-content/uploads/2008/01/080120_cpu.png) The traffic is still the same. * Any ideas?

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](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](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. * Thread Starter [miccom](https://wordpress.org/support/users/miccom/) * (@miccom) * [18 years, 2 months ago](https://wordpress.org/support/topic/high-cpu-load/#post-684368) * 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: * [http://www.greensmilies.com/wp-content/uploads/2008/01/080117-24_cpu-week.png](http://www.greensmilies.com/wp-content/uploads/2008/01/080117-24_cpu-week.png) * 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… * Thread Starter [miccom](https://wordpress.org/support/users/miccom/) * (@miccom) * [18 years, 2 months ago](https://wordpress.org/support/topic/high-cpu-load/#post-684416) * 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 Viewing 4 replies - 1 through 4 (of 4 total) The topic ‘high cpu load’ is closed to new replies. ## Tags * [high cpu load](https://wordpress.org/support/topic-tag/high-cpu-load/) * [preg_replace](https://wordpress.org/support/topic-tag/preg_replace/) * In: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) * 4 replies * 1 participant * Last reply from: [miccom](https://wordpress.org/support/users/miccom/) * Last activity: [18 years, 2 months ago](https://wordpress.org/support/topic/high-cpu-load/#post-684416) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
