hello
i am getting around 30000 hits on my server/day and somehow i feel that many of my visitors arent able to view my site at all times.
my stats have fallen.
i have been told to check these settings in httpd.conf
can you tell me what settings should i keep to accomodate max traffic on my server and at the same time keep my server stable/.


#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 180

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive Off

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.

KeepAliveTimeout 15

I was just wondering what are the specs for your server? Example Ram, CPU,

[Digger]

its a dual 2.8 GHz xeon
1GB ecc ram
can you help?

You may want to turn KeepAlives on as it saves a lot of TCP overhead by reusing connections. Also, check if your Apache is forking enough handlers to deal with the requests and set a limit on the maximum number of connections. The firewall may also be a bottleneck if you have conntrack on. You need to increase the connection tracking limit (if you are running Linux).

Yes, but KeepAlive also ties up an apache until the client times out. Even at a few seconds, that can tie up a lot of apaches (and the associated memory) doing nothing productive.

30,000 really isn't that much, unless it's a lot of large stuff. See what your MaxClients is set for. It shouldn't be above 1 per 2MB of RAM, but you should only need 150 or 200 with that traffic level.

Might try tweaking these settings:

MinSpareServers 5
MaxSpareServers 10
MaxClients 150

Also you should look at a stats package to see if your Too Many Connections error is shown or create a custom error page for it which logs the accesses. If you find that this page is being hit lots then up the max clients.
