Hi everyone,
I have a little problem that no matter what I do, I can't increase the concurrent web requests and connections to my Cherokee. As you will see below, no matter what I do, the maximum number of file descriptor for user www-data remains at 1024 and poor Cherokee will not be able to service more than 1024 concurrent connections ... could you let me what I am missing here? I have also modified Cherokee to report concurrent connections and the logs will confirm above as well: LOG::: CPU42% LdAvg 0.240000 AvgRspT 20 TtlConns 911 TtlHitThrshld 10 MinRspT 3 MxRspT 317 Duration 1009 Thrshld: 200 Above log tells us that the load average of system is 0.24 (during last 60 seconds). And CPU utilization is around 42%. And Average response time is 20 ms and we have had 911 connections/requests within the last 1009ms. Acceptable response time threshold is 200ms and 10 connections exceeded that limit while the minimum response time was 3 ms and maximum response time was 317ms. Here is what I have done: cat /etc/security/limits.conf: * soft nofile 65535 * hard nofile 65535 sysctl -w fs.file-max=300000 ulimit -n 100000 cat /proc/sys/fs/file-max will give us 300000 added new limits at the top of /etc/init.d/cherokee-webserver as limits are inherited through fork(): ulimit -u 100000 ulimit -n 200000 =============================== ulimit -a for root: =============================== core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 16382 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 100000 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) unlimited virtual memory (kbytes, -v) unlimited file locks (-x) unlimited =============================== ulimit -a for www-data user: =============================== time(seconds) unlimited file(blocks) unlimited data(kbytes) unlimited stack(kbytes) 8192 coredump(blocks) 0 memory(kbytes) unlimited locked memory(kbytes) 64 process unlimited _/*nofiles 1024*/_ vmemory(kbytes) unlimited locks unlimited Thank you very much, Navid
