Pbl

I’ve seen Pen and Pound discussed, but has anyone used PBL (http://
plb.sunsite.dk/ha.html) in their rails setup?

Yeah I saw this recently too. It looks really interesting, but I don’t
have anything to test it on at the moment.

FYI: The current status on Pound and Pen though is they’re only good
for small setups at around 3-5 mongrels. I’ve ran into a few folks who
were trying to push Pound toward 30-40 or more and it was killing them.

It’s not suitable for load balancing mongrel, unless you want to have
an application spread over many machines with one mongrel per server.
The config accepts multiple IP addresses, but you can only add one
port to connect to. I just tested it out and confirmed that:

servers_ip 127.0.0.1
servers_port 8000 8001 8002

does not work.

Or you can just have multiple IPs on one machine. But this seems a
very odd limitation =)

Sure, but I doubt that would work very well with mongrel_cluster.
You’d have to write something that started each mongrel on a different
IP.
Bleh.
