What’s the difference between the jitter buffer mentioned [here](https://www.wowza.com/docs/how-to-turn-on-an-rtp-jitter-buffer-and-packet-loss-logging-rtp-and-mpeg-ts#configure-an-rtp-jitter-buffer0)  
and the sort buffer mentioned [here](https://www.wowza.com/docs/how-to-fix-unaligned-video-and-audio-with-a-server-side-sort-buffer)

I’ve noticed a correlation between cpu utilization and rtpDePacketizerPacketSorterFlushTime. A flush time of 10 uses significantly more cpu utilization than a flush time of 50. How does one determine the proper value for these parameters? What’s the effect of a larger or shorter flush interval?
