Hi Owen - thanks for replying. I'll try the suggestions you mentioned for the log. Some pages do rely on DB access AND also mounted drives. However, I also find that even the front page (index.html) can be very slow, as I described earlier. Thanks. -----Original Message----- From: Boyle Owen [mailto:Owen.Boyle@xxxxxxx] Sent: 07 June 2005 13:22 To: users@xxxxxxxxxxxxxxxx Subject: RE: [users@httpd] web server sometime very slow > -----Original Message----- > From: Michael Simpson [mailto:Michael.Simpson@xxxxxxxxxxxxx] > Sent: Dienstag, 7.

Add %T or %D to the LogFormat and then look for slow requests. Then try to figure out why. Also, do the pages rely on any backend process (eg, DB access etc.) or network latency (mounted drives etc) Rgds, Owen Boyle Disclaimer: Any disclaimer attached to this message may be ignored. > > Some details: > > Apache 2.0.45 (Win32), PHP/4.3.9 > httpd.conf: HostnameLookups Off > > ---------------------------------------------- > Michael Simpson > Systems Development > Express Newspapers > Number 10, Lower Thames Street > London, EC3R 6EN > (switchboard) 0871 434 1010 > (direct line) 0871-520-7225 > (IT fax) 0871-520-7799 > mailto:michael.simpson@xxxxxxxxxxxxx > ---------------------------------------------- > > > > The NMA: Opening Up Newspapers http://www.nmauk.co.uk > > Visit Express Newspapers and OK Magazine online picture archive at > http://www.expresspictures.com/ > > ###2004### > ________________________________________ > Any views or opinions are solely those of the author > and do not necessarily represent those of Express Newspapers > ________________________________________ > The information transmitted is intended only for the person > or entity to which it is addressed and may contain confidential > and/or privileged material.If you are not the intended recipient > of this message please do not read ,copy, use or disclose this > communication and notify the sender immediately.
