    Average Transfer Speed=Average Throttling Rate?


    Hi all,
    I am using Platespin protect 10.3, and source -> target 1st replication
    thru 2M WAN link, Compress rate set to Optimal.

    Workload 1:
    Replication Transfer Summary
    Average Transfer Speed: 0.33 Mbps
    Effective Compression Rate: 84.33%
    Duration: 1d 4h 12m 54s
    Total Uncompressed Data: 24.8 GB
    Total Data Transferred: 3.9 GB
    Total Files Transferred: 6,492
    Bandwidth Throttling: Start Time End Time Selected Throttling Rate
    Average Throttling Rate
    11/19/2012 11:53:42 PM 11/20/2012 9:00:02 AM Off 0.93 Mbps
    11/20/2012 9:00:02 AM 11/20/2012 5:04:18 PM 1.00 Mbps 0.65 Mbps
    11/20/2012 5:57:12 PM 11/20/2012 7:00:08 PM 1.00 Mbps 0.84 Mbps
    11/20/2012 7:00:08 PM 11/21/2012 4:05:41 AM Off 0.93 Mbps

    Workload 2:
    Replication Transfer Summary
    Average Transfer Speed: 1.33 Mbps
    Effective Compression Rate: 67.74%
    Duration: 13h 39m 3s
    Total Uncompressed Data: 23.5 GB
    Total Data Transferred: 7.6 GB
    Total Files Transferred: 6,826
    Bandwidth Throttling: Start Time End Time Selected Throttling Rate
    Average Throttling Rate
    12/4/2012 4:12:53 PM 12/4/2012 7:00:08 PM 1.00 Mbps 0.63 Mbps
    12/4/2012 7:00:08 PM 12/5/2012 5:50:43 AM Off 1.51 Mbps


    Q1: Why workload 1 Average Transfer Speed not = Average Throttling Rate
    workload 2 Average Transfer Speed = Average Throttling Rate?

    Q2: What is different between Average Transfer Speed and Average
    Throttling Rate?

    Re: Average Transfer Speed=Average Throttling Rate?


    The Average Transfer Speed is not always 100% accurate. It is a simple
    calculation using the amount of data transferred and time taken. In
    actuality both workloads may have had the same transfer rate, but if one
    had a networking issue at one point that would extend the time of the
    transfer (and lower the average transfer speed). Do not expect that
    number to be entirely accurate.

    Average Throttling Rate is an indication of the throttling applied. For
    example, you might have set throttling to 2Mbps. We might, on average,
    throttle to 1Mbps. That's what this number means.
