TOPIC

    This article provides general performance expectations for QuickTime Streaming Server.

DISCUSSION

    The following scenarios are examples of the performance available from Quicktime Streaming Server.

    Expected Performance

    Scenario One: Internet Streaming
    Many, small connections to server (low bandwidth, high volume)
    • 1000 client connections
    • viewing 150 different movies
    • 22 Kbps streaming rate

    Scenario Two: LAN Streaming
    Few, large connections (high bandwidth, low volume)
    • 50 client connection
    • viewing 3 different movies
    • 1.5 Mbps streaming rate

    Factors Affecting Performance

    These factors affect the server's performance:
    • available network bandwidth
    • available memory
    • other services or processes open on the server
    • movie size
    • frame rates
    • compression type
    • number of tracks
    • frame size (pixels)

    Storing movies on UNIX File System (UFS) and Mac OS Extended (HFS Plus) formatted volumes offer the same performance; there is no difference.

    Suggestions

    Always hint in optimized format--this creates larger files, but improves performance. (QuickTime 4 Pro is required in order to create hinted movies.)

    If you expect heavy streaming usage, do not open other services on the server you are using for QuickTime Streaming.
