Im not sure if this is still true.. but i think the problem with round robin dns is "dns-caching".. you probably wont get the round-robin effect since dns queries may be cached?
Some loadbalancers that i know and have seen in action are Pen,pound, and smartpeer. I was able to go into the details of differences in terms of performance/features etc. Also, i think you can achieved a high-available server by setting up a LVS? this is in the linux 2.6.x kernel it is also worth considering the other features of the available load balancers such as health monitoring of the http servers so that when 1 http server crashed the load balancer will be smart enough not to direct connections to it. > why not use round robin dns? > i think thats what google and yahoo use if im not > mistaken. > > > > pound <http://www.apsis.ch/pound/> > > > or use squid plus a redirector script/program > > > > Has anyone compared the performance of Pound -- > which does not cache > > content, but merely passes them on to the nodes of > the cluster behind it > > -- with Squid plus a redirector program? > > > > --> Jijo __________________________________ Celebrate Yahoo!'s 10th Birthday!
