I'm using Wowza Stream Engine for Live Streaming and it works great, i want to provide VoD content and want to find bottlenecks of my servers .
I have some questions about my hardware requirements !
my servers have 2x4core CPU + 32GB RAM , The edge servers pull the content from the origin server
How many VOD concurrent users each Edge server can handle with normal HDD storage?? and how many with SSD? (single bitrate and normal quality)
if the HLS decrease performance of my servers in Live and VOD comparing it to rtmp?
what about time-shift ? how many concurrent users each server can handle with 2 hours ABR time shift over HLS?
Is it important to increase the RAM in VOD and Time-Shift ? does the content catch on RAM?
How can i improve the performance ?
