Thread: CPU Usage X Memory

    Default CPU Usage X Memory

    Hi All,

    In a regular VoD operation, what's the most important concern: CPU power or Memory?

    Disk speed will usually be the first bottleneck in a VOD application. Then network bandwidth. Regarding CPU vs. Memory, I'd say RAM is more important in VOD applications, CPU in transcoding applications. Not setting your Java heap too high and leaving some RAM for OS file caching might help also.

    A commodity 7200RPM drive is going to get somewhere around 30MB/s read speed. But worst case scenario random access reads can bring that down to below 1MB/s transfer rates. RAID arrays with 15kRPM drives or SSDs will help a lot.
