HP Apache higher cpu utilization

Shivkumar — Mon, 13 Mar 2006 13:45:25 GMT

Hi,

We have upgraded HP Apache to 2.0.54 and 2.0.55 on HPUX 11i.

We observed that "restart" take more cpu than start and stop command.

Can anyone suggest what could be the issue ?

Thanks,
Shiv

Shalom Shiv,

I'd like to see the data that led you to this conclusion.

It is however not uncommon for new quirks to work into new versions of the software. Performance enhancements and such. New bugs.

Most HP-UX startup scripts don't accomodate a restart option. This in itself is special, but I think the code in use is the same as stop followed by start.

Which leads me to question how you came to this conclusion.

I shall watch the thread a while and respond again if warranted.

Steven, I don't have access to the box having issue. I had received this issue from a business partner. But i think $./apachectl restart command is a kind of soft start of apache web server and this command enables us not to disconnect the existing web client. Regards. Shiv

Hi Shiv,

Have you done any performance tweaks for HP Apache ? Just check the official guide,

I hope restart is done as ./apachectl stop ./apachectl start. Can you post this:

Telnet session 1:

# ./apachectl restart

Telnet session 2:

Get cpu information for apachectl process.

Telnet session 1:

# ./apachectl stop
# ./apachectl start

Telnet session 2:

Get cpu information for apachectl process.

It will give more informations.
