Load balancing eZ Publish?

Jonathan Dillon-Hayes	Tuesday 22 March 2005 11:07:16 pm Hello: I'm looking into Load Balancing solutions for eZ Publish. We currently have a solution implemented for a few clients, but it's based on the LVS project. I'd like to hear if anyone else is load balancing their systems, or clustering eZ Publish, and what approach you've taken. Anyone have experience here?

Hello:

I'm looking into Load Balancing solutions for eZ Publish. We currently have a solution implemented for a few clients, but it's based on the LVS project.

I'd like to hear if anyone else is load balancing their systems, or clustering eZ Publish, and what approach you've taken.

Anyone have experience here?
