MY BUILD

I am using a Linux CENTOS 6 server with Plesk 10.4.4 Apache and Wowza Media Server 3. The server is a quad core and has 12GB RAM.

WHAT HAPPENED BEFORE

I was having a problem with some Wordpress websites that utilize lots of CPU when running custom CRON jobs, so I looked for ways to make the server faster.

I first installed eAccelerator, and that caused alot of my MYSQL tables to crash and some other problems arose. I uninstalled it and everything went back to normal.

Next, I found people were getting some good results with APC and Memcache, so I installed them after a yum update.

WHATS HAPPENING NOW

All RTMP streamed videos are buffering after playing only a few seconds, but the server load is practically nothing. This was not happening before all those changes.

load average: 0.01, 0.04, 0.06

Here's an example (please see the video in the header section, they rotate each page load): http://activemd.net/index.php

WHAT I DID TO TRY TO FIX IT

I disabled APC and removed memcache.

I am still having the same problem of every video I try to stream. They all buffer after only a few seconds.

Another observation I'll make is that APC and memcache seemed to make my PHP pages load slower. After disabling those modules, they now load faster.

THE QUESTIONS

  1. What can I do to stop my videos from buffering?
  2. Could one of the changes I made have affected the way my videos are streaming?
  3. What are some troubleshooting steps I can take to isolate the problem of my videos always buffering?

Any help is much appreciated, Rick

Did you tune your Wowza server based on your hardware ? If no, follow this link http://www.wowza.com/forums/content.php?46

There is not a server side buffering in the wowza media server.

If you are trying to stream video to n number of devices. I recommends you use a standalone Wowza media server.
