Versions: iChain 2.0, 2.1

For at least iChain v2.0 and v2.1, I recommend putting these three set parameters:

- set tcp delayed ack=off
- set tcp nagles algorithm = off
- set tcp maximum initial window = 4

Without these parameters an upload to the web server though iChain took 10x more time than directly to the web server, i.e., 50s , 5s.

With those parameters the same upload is taking 6s with SSLizer enabled. Downloads are faster, too.

This link explains one implication of the NAGLE set parameter: http://developer.novell.com/ndk/doc/nwprotlb/index.html?prot_enu/data/hjc6o3fy.html

Try it!
