Factors aecting performance
is section explains how performance for Flash Media Server 3 is aected by dierent condi-
tions. Measuring performance increases is done by comparing the number of concurrent
streamsforagivenCPUutilization.Knowinghowmanystreamsaserverwillsupportwillhelp
you understand how many servers you need to deploy.
e number of streams a server can deliver is dependent upon a number of conditions, including:
• Protocol—RTMPisthehighestperformingprotocol,followedbyRTMPE.
• Video bitrate (quality)—e lower the bitrate of your video, the more concurrent streams can
be delivered by your server.
• Platform—YoucandelivermoreconnectionswithlessCPUusageutilizingLinuxRedHat4.
• Hardware—HardwaresuchasRAM,diskspeed,CPU,andnetworkspeedwillallinuencethe

• Application complexity—Ifyoudeploycustomplug-insordevelopcomplexserver-side
application logic, your performance may increase or decrease.
• Usage—e way your users interact with your video will impact the server performance.
