Comment(by robgjansen):
I just uploaded a
[https://trac.torproject.org/projects/tor/attachment/ticket/5336/20120808-ec2
-creditbuckets-combined.pdf graph of client performance]. See #6401 for a
description of the Tor network model and the client model.
There are 3 experiments here, all run with tor-0.2.3.16-alpha:
Load distribution for vanilla Tor:
{{{
TYPE #XFERS GiB %
im 34735 0.033 0.075
web 85779 26.178 59.376
bulk 1586 7.744 17.565
p2p 596397 9.100 20.641
perf50k 1896 0.090 0.205
perf1m 965 0.942 2.138
TOTAL 721358 44.088 100.000
}}}
Load distribution for 10 MiB credit cap:
{{{
TYPE #XFERS GiB %

web 55965 17.079 47.710

p2p 347047 5.296 14.793
perf50k 1517 0.072 0.202
perf1m 1000 0.977 2.728
TOTAL 429783 35.798 100.000
}}}
Load distribution for bandwidthrate credit cap:
{{{
TYPE #XFERS GiB %
im 7217 0.007 0.031
web 29426 8.980 40.783
bulk 2379 11.616 52.755
p2p 48498 0.740 3.361
perf50k 841 0.040 0.182
perf1m 651 0.636 2.887
TOTAL 89012 22.019 100.000
}}}
It looks like the credit caps are reducing overall network load, mostly
from the web clients. Bulk load seems to be increasing. The effect seems
greater with smaller credit caps.
