How fast is RabbIT?
That depends on how you measure fast. Loading times can vary from 20 times as long to 0.2 times...

I do not consider this a good test, but here is a test:

doing a "time wget -o ../log -i ../localurls " for my local web site which consists of 182 pages/images from the standard apache/mod-perl/mod-ssl documentation.

These values are based on RabbIT 2.0.14. Performance is increased in later versions.

The values are some kind(I decided the "average" value) of approximate average over several runs.

Method	#Bytes	%	Time loopback	*	3 kB/sec line (28.8 modem)	*	6 kB/sec line (56 modem)	*
Apache: on localhost, plain files.	2063445	100%	0.26 seconds	1	753 seconds	1	377 seconds	1
RabbIT: no filtering, no compression.	2063445	100%	1.4 seconds	5.38	754 seconds	1	378 seconds	1
RabbIT: no filtering, compression of text/html and text/plain.	726770	35%	2.7 seconds	10.4	238 seconds	0.32	121 seconds	0.32
RabbIT: parse compress and filter away ads, backgrounds etc...	742822	36%	4.56 seconds	17.5	245 seconds	0.33	125 seconds	0.33
RabbIT: all of site in cache, compressed and filtered	742822	36%	0.57 seconds	2.2	241 seconds	0.32	121 seconds	0.32

What conclusions can be drawn from this?

It should be clear that you should not use RabbIT if you are surfing on a fast LAN. However if you have a modem RabbIT will make a difference. As can be seen from the above page loading times less than half of the original should not be uncommon.
