httpd.conf help on a 256mb VPS by webkeepers
I am using a VPS provided by webkeeprs, and actually my site got quite amount of traffic everyday, sometime when it at peak, by then website won't load, and got blank page.
Check with the resourses used, I only got 256mb in ram, and it always show "RED" and which had consumed 240mb on ram already at peak time.
Here is my setting of my httpd.conf file, I am looking for some expert who may give me a hand on this setting:

Set KeepAlive=Off and MaxRequestsPerChild to something greater.
How is your swap memory configured?

256 MB RAM is simply not enough to sustain that Apache configuration.
I'd cut the Start/Min/MaxServers by half.
Reduce ServerLimit/MaxClients drastically, to maybe 15 or 20.
And increase MaxRequestsPerChild to maybe 2000. (When an Apache thread has served this number of requests, it s killed off and a new one is spawned. With it set to 30, your Apache is constantly killing/respawning threads.)
For MySQL, disable innodb unless you really need it. It uses a big chuck of memory.
To see your memory usage, run top and press shift-M to sort the output by memory usage.

Is there a reason your using apache and not a lighter weight http server such as nginx or lighttpd ? they would be better suited.

Is there any reason why you can't increase the amount of memory? If you start limiting the maxservers/maxclients etc. you could end up preventing visitors from accessing your sites (timeouts etc).

You can only optimize this so much. I agree, change out to lighty or nginx and minimize whatever services you're running. But that will only buy you so much extra headroom. I think in the end you're just going to have to increase your VPS memory.

How much are you paying per month? If its the upper 50's-60.. you could get a cheap dedicated for that price with double the memory. (unmanaged of course)
256mb is pretty low.....GottaDeal.com - Hot Deals & Coupon Codes. Why Pay Retail?http://www.gottadeal.com/images/bann...eal-234x60.gif

midnightsoftware:
my VPS provided not allowing JUST increase the ram, told me must shift into a higher cost plan. limiting the maxservers/maxclients really will block visitor to access? I currently got around 1500ip coming in everyday, would that hurt to set maxser/mascli low?
Nnyan & Twista:
i really going to find another vps provider by the end of coming feb, since i am on a annual plan. i am on a plan which is only cost me $10 per month, and plesk, and virtuozzo are included, really cheap eh. But i just want my site to be self-feeding, no extra money from my own pocket. am i so wrong? or what another options will you suggest?
Thanks for helping!
