Hi, I set up COOPAD on the new server today and see very poor performance getting ADs. I have profiling in my application so I know exactly time spent on CoopAD data retrieval compated to other things: mysql> select avg(coop) from requests_050417; +-----------------+ | avg(coop) | +-----------------+ | 5.0249083531577 | +-----------------+ 1 row in set (0.00 sec) I see 20ms ping time and no packet loss so it is not network problem. On other servers on other hand I do not have this problem. Is it because coop hash file is still populating on this new server ? For debugging purposes my web site is http://www.ljsearch.net
