 * Hi,
 * I have Crawler activated.
 * I see lots of rows in access.log like:
   (IP) – – [13/Jul/2025:17:03:59 +0200] “
   GET / HTTP/1.1” 200 12825 “[http://www.mydomain.com/wp-admin/admin-ajax.php?action=async_litespeed&nonce=xxx&litespeed_type=crawler&#8221](http://www.mydomain.com/wp-admin/admin-ajax.php?action=async_litespeed&nonce=xxx&litespeed_type=crawler&#8221);“
   lscache_runner Mobile iPhone” 0.002 0.002
 * For example 10 rows per 1 second, 600 rows in 1 minute.
 * My webhosting provider limits PHP workers.
 * How much PHP workers does your crawler use?
 * Is it 1 PHP worker or more PHP workers in the same time?
 * Regards,
   Jiri Polacek

 * by default , it’s 3 threads crawler
 * you can add `define('LITESPEED_CRAWLER_THREADS', 1);` to your wp-config.php ,
   next line after `<?php` , to define it to 1 thread only to reduce PHP concurrency
