this is just wasting of time, no?

build and test on legacy 2.4.x kernel and after doing it -
again build and test on 2.6.x kernel before production use.

make production high traffic load-balancer
on legacy 2.4.x kernel - is not good idea.

if use "very cheap hardware" for "high traffic load-balancer" -
very cheap hardware may have low reliability and very low performance.

absence of failures and absence of lags/overloads
IMHO has more priority over "hardware low price".

especially if in future load balancers
feel very high load under DDoS attacks.

WRT-54G has slow CPU, low RAM, and it is bad candidate for load balancer hardware.

using DSL( or DSL-N ) and WRT-54G as high traffic load-balancer
software and hardware is useless and harmful recommendations, IMHO.

but using for frontends modern hardware and OS allow use its
at least also for nginx caching in order to reduce
backends load and quantity, and so on...
