LVS vs HA Proxy

[howard chen]

>From the HA Proxy page:

It said:

Linux Virtual Servers (LVS)
Very fast layer 3/4 load balancing merged in Linux 2.4 and 2.6
kernels. Should be coupled with Keepalived to monitor servers. This
generally is the solution embedded by default in most IP-based load
balancers.


This does not tell anything abt performance, or stability, anyone want
to comments abt this?
