Hi. Thanks that you took the time to answer.

Dirty Harry is my second name :)

Jokes aside, tweaking and tuning is what I like and performance is my high. I do not believe in silver bullets. I used to work for a huge company as a consultant and even though how much money they poured into the arch it never performed since they always needed everything to solve everything. For instance having Apache load all modules possible and turn on all options, having all java webapps in one BIG container etc. Stupid and waste of money and resources and in the end user experience.

The requirements of our load balancing is quite simple since the nature of our architecure is as well. Basically all dynamic requests (which needs LB) should go to and static ones to and soon to come

I will test haproxy on Ubuntu Hardy 64bit, 8GB, quad-core 2.4MHZ, RAID-1and apply a sysctl.conf which I normally use on our webservers. Is Linux bytw OK for the job ? Know some people do not like the schedulers in Linux. Want to have a look at the sysctl.conf ?

I think I used 1.3.XX (perhaps .12 since it ships with Ubuntu these days). The webapp only had about 20 reqs/sec so it worked just perfectly. The main reason why I look at HAProxy is because my friends and some former colleagues recommends the product.
