[ECOS] Network characterisation / net stack performance.

["Richa Jain Mehta" <richa at cradle dot com>]

Hello,

Does any one have any figures for network characterisation of eCos?
I got the following nos. on our target. I'd like to know how they compare to
other platforms.
Any information is welcome!!!

Thanks and regards,
Richa.
