hi folks, can someone give/point some tips for tuning the tcp/ip stack on a linux box for handling really large number of connections...?
W Richard Steven's books(TCP/IP Illustrated and UNIX N/W Programming) has lots of answers. There are no quick fix solutions. Most of the decisions are tradeoffs between one parameter or the other. So you will need to understand the consequences before tuning.
how would this tuning be different from tuning for fast routing?
Depends upon whether QoS is enabled while routing.
