CQS transmits on 12 multicast lines, which distributes the symbols for faster
processing. The current capacity is 75,000 quotes/second for each multicast
line, and 750,000 quotes/second for all 12 in total. The total line is plotted
in black and was divided by 10 to fit into the same scale. These charts show
1ms intervals using CQS timestamps and the rate is scaled to show the per
second rate. What we have discovered is that the total line never gets higher
than 750,000 in any 1ms period -- but it should. This indicates to us, that
saturation is occurring whenever the total line approaches the 75,000 line on
these charts. There is also a bandwith limitation which is related, but not the
same as the message rate. This is what may be limiting the lines below
75,000.
