The current (probably April 2001) issue of Linux Journal has an article from
a pair of Erikson engineers who were looking at using LVS to front end a
bunch of diskless web servers. They only tried NAT in the article, and on a
500mhz pIII got about 1700-1800 connections per second before it topped out
(tested using Web Bench). Direct connection to the servers yielded around
8000 connects/sec. What wasn't clear was where the bottleneck was. Would a
Ghz class pIII double the throughput, would better NIC's help, is there a
limitation of the Linux stack? They were going to try the DR mode, but
hadn't by press time. I believe they were using the stock 6.2 RedHat
Piranha dist. The 2.4 kernel is reputed to have a more efficient network
stack, does anyone have a feel for the amount of perf improvement for LVS
(understanding that Web Bench is a benchmark and nothing more)?

I took a quick look.
Seems like a low-end solution. (8000000 connections per hour
works out to 2k connections per second).
