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     %
 im      21724   0.021   0.058
 web     55965   17.079  47.710
 bulk    2530    12.354  34.509
 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.
