    I voted that way instead of too broad/book answer to at least give you some things to start down. Your question isn't specific enough. We don't know your server config, nginx config, webserver stats, performance metrics, etc. – TheCleaner May 16 '14 at 17:31
  • @TheCleaner i actually don't know what is the configuration REALTED to slow playing videos issue so i can put the configuration to see it – user209827 May 16 '14 at 17:33
  • @user209827 ... well if you don't know, how/why do you expect us to be able to divine the answer for you? We're not clairvoyant. – HopelessN00b May 16 '14 at 17:36

Here's what you can do to your base system:

# yum install tuned tuned-utils
# tuned-adm profile throughput-performance

See the chart below. These settings will at least make the I/O scheduler aware of what you're trying to do and help with some better sysctl and storage subsystem defaults. Can you test with this and report back? You can revert the settings to default with tuned-adm profile default
