Hi, I need some advice. I received 100.000 (100k) unique/hour, serving static files (text files) using PHP calling the txt file using ajax refreshed with 60 seconds intervals. Server load was quite stable 1.2-2.0, and iowait was quite good bellow 10% utilization. However litespeed seems to be very slow on it. Running Litespeed 3.3.18 enterprise (two CPU license), RHEL 5.2 32 bit with PEA Kernel to support 8GB RAM. On this server Dual Processor Quad Core Xeon 5430 - 2.66GHz 8GB RAM RAID 1 15k RPM 147GB HDD (Just for web) Litespeed Max Connections = 9000 Max Keep-Alive Requests = 4500 Connection Timeout (secs) = 50s lsphp5 setting Max Connections = 80 PHP_LSAPI_MAX_REQUESTS=700 PHP_LSAPI_CHILDREN=80 Initial Request Timeout (secs) = 60s Memory Soft Limit (bytes) = 350 Memory Hard Limit (bytes) = 400 Process Soft Limit =200 Process Hard Limit = 200 MRTG Reported the bandwidth uses 50Mbps average and our public port is 100Mbps Please give me some pointer on improving this.
