Re: [us...@httpd] High load apache

If you've already narrowed it down to php, jmeter probably won't help you further. Are you getting any error messages in your apache log? If not, check the log level in your php.ini file and set it to log everything. Is there not a list or forum for horde? Try posting there. John On 09/14

Sorry Paras, I didn't catch it right , then the behavior is : Database based (Performs Wrong) Non Database based (perform good) html files (performs good) is this right ? Asuming this is the case, then you should check your database server to see if you're seeing stress signs on it. Also, if y

Just confirmed that the runtime wait is happening to all the database based and non database based php scripts and with plain html files it is fine. Ideas? Paras. On Tue, Sep 14, 2010 at 12:46 PM, Paras pradhan wrote: > Yes horde is based on PHP and Mysql. But the page I am hitting with ab is >

Re: [us...@httpd] High load apache

Yes horde is based on PHP and Mysql. But the page I am hitting with ab is just the login page and no database involved. Paras. On Tue, Sep 14, 2010 at 12:43 PM, Pablo Garcia Melga wrote: > I'm not familiar with Horde, does it run against a database server ?, > based on the information you provi

Re: [us...@httpd] High load apache

I'm not familiar with Horde, does it run against a database server ?, based on the information you provided, there's seems to be something else preventing the apache to serve the requests on time. On Tue, Sep 14, 2010 at 2:19 PM, Paras pradhan wrote: > Pablo, > Here the o/p: > command: ab -t 60

Re: [us...@httpd] High load apache

I got almost the same result as yours with a small test php script. But with the login page of horde, I am getting a small number of requests processed. I am assuming my tuned apache is fine and its the bulky horde php scripts that are hitting me. But still looking around the solution.. I have memc
