Upon saving the Permalink setting? When the . htaccess file is written after saving?

None match your situation, if what are saying is true that it happens even when you choose the Default structure. * > i think this is becuse of mod_rewrite wordpress problem * If what you’re saying is true, and this happens even when you save the Default structure, then it’s not mod_rewrite, because Default doesn’t use mod_rewrite. * Which, of course, brings me back to the last reply, we need details. We can’t even begin to guess at a solution without them. Do you manage your own server? What are the specifications? What is the web server and it’s version, is mod_rewrite installed, what is your PHP version, and have you tried with all plugins temporarily deactivated? * Thread Starter [BF100](https://wordpress.org/support/users/bf100/) * (@bf100) * [11 years, 11 months ago](https://wordpress.org/support/topic/permalink-cpu-100/#post-5015092) * > a month after WordPress 3.9.1’s release which has been downloaded 24 million > times. * i have this problem in 6 month past ( not just in 3.9.1 version ) * > if what are saying is true that it happens even when you choose the Default > structure. * i said every one -Default ! in Default cpu = 0.2% * > Do you manage your own server?

Because there has to be something unique to your configuration causing this. * WordPress powers about 22% of the internet (the entire internet), and I haven’t seen a report like this for 3 years. * It’s either something in your server configuration or your plugins (though you have claimed to have deactivated those). * Was there definitely nothing in the server logs at the time of the CPU spike? * Thread Starter [BF100](https://wordpress.org/support/users/bf100/) * (@bf100) * [11 years, 11 months ago](https://wordpress.org/support/topic/permalink-cpu-100/#post-5015165) * plases say which log file do you want ?
