[Rabbit-dev] Rabbit-dev Digest, Vol 18, Issue 3

[Luis Soltero]

The only way we have been able to determine the efficiency of rabbit is using the network feature of the firebug plugin
for firefox.  The chrome console also has a similar feature.

This tool will tell you exactly the amount of speed up you get with the proxy.  First you flush browser cash and disable
the proxy settings and then browse the pages you are interested in.  Then you flush the cache again and enable proxy and
do the browsing again.  You then manually computer the ratios.  On average you will find about 3-5x improvement in
performance.

It would be really nice to do this system wide for all users and all pages.  The above only works for spot checking and
is quite labor intensive. 

Take care.
