parallelized requests

[Jan Pfeifer]

Thanks for the answer Brad.

I also noticed that the PHP client does the same thing. So if the whole network packets fits the buffers, I believe this would be as good as if it were parallelized. Sweet :)

Iirc, the Perl library sends all the requests, then reads all the
responses (but in order, not as they're readable).  That partially
mitigates the multiple-server round-trip pain.

Making it read from the sockets back in order would matter more if
memcached weren't so damn quick.

I'm setting up a cache layer here at work that will
probably be composed by 4 servers (or maybe 2 dual core ones). For our
use case, we might need to get on average 10 keys to build a web page,
but possibly up to 200 small key/values, or even more in very rare
cases.

My question is: do the C or the PHP libraries parallelize
the requests for the keys to the different cache servers when using the
multi-key request ? Or does it fetch the keys one server at a time ?

thx in advance for any answers or pointers :)

ps.:
sorry
if this have been asked before (seems a basic question to me), it's the
first time I'm using memcached, and I couldn't find anything by
searching in the list.
