Hi All,
I am using Apache as a forward cache proxy and configured with prefork module using below settings.
<IfModule mpm_prefork_module>
StartServers 200
MinSpareServers 50
MaxSpareServers 100
ServerLimit 1000
MaxRequestWorkers 1000
MaxConnectionsPerChild 1000
</IfModule>
Ulimit is configured with
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 63470
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 2048
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) 63470
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
Kernel settings is configured as
net.core.rmem_max = 4194304
net.core.wmem_max = 4194304
net.ipv4.tcp_rmem = 4096 65536 4194304
net.ipv4.tcp_wmem = 4096 65536 4194304
net.core.somaxconn = 4096
net.ipv4.tcp_fin_timeout = 10
net.ipv4.tcp_max_syn_backlog = 1024
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_window_scaling = 1
But no of concurrent connections is not increasing above 250. Please let me know why connection count is not increasing 250 with above configuration.
Thank You
