We are facing very high response time in delivering the chunks ( Chunk Size 6 sec) to requested server. Whenever there is request/network utilization on Wowza server for more than 2.5 -3 Gbps, response time increases to 20-30 sec and when utilization is less than 2 Gbps , response time is less than 1 sec . At same time CPU Utilization increases from 10 % to 70% . And most of CPU is consumed by java process.
We are using HP DL 380 Gen 8 with 192 GB RAM and CPU 48 Cores. Network Interface is of 20 Gbps bonding.
OS is CentOS 6.5 with Kernel Version 2.6.32-431.el6.x86_64.
