I have one of my websites on the first page of digg - so a lot of traffic

but there is a problem - many users are unable to see it and not even all resources on my server are used:

Processor Name Intel(R) Pentium(R) D CPU 2.80GHz
Vendor ID GenuineIntel
Processor Speed (MHz) 2793.167
Processor Name Intel(R) Pentium(R) D CPU 2.80GHz
Vendor ID GenuineIntel
Processor Speed (MHz) 2793.167
Total Memory 2069320 kB
Free Memory 1182704 kB
Total Swap Memory 2031608 kB
Free Swap Memory 2031608 kB



- any settings i need to change??

Thanks
 
If your website got digged and has become unresponsive, it may be because the bandwidth line is saturated from all the traffic. Do you know what kind of port speed you get (10mbps or 100mbps)? Also, can you login via SSH and run the "top" command to get the load average for your server to see if the CPU is being overloaded?
 
i edited httpd.conf to: (hopefully now more connectons are alowed) - anyone?

i put
KeepAlive to Off

now it works better

but still some long term settings are needed
 
If your website got digged and has become unresponsive, it may be because the bandwidth line is saturated from all the traffic. Do you know what kind of port speed you get (10mbps or 100mbps)? Also, can you login via SSH and run the "top" command to get the load average for your server to see if the CPU is being overloaded?

i am on 100mb line

now with keepalive set to off it works fine

the problem is that by default some variables like max number of simultenious connections are set really low

now it seems like it works fine

still on the first page of digg, one of the first 5 stories :D
