Inconsistent performance

[Matthew Gibble]

I am a bit of a newbie to memcached, although I have
played around with it for about a month or two now.  I
am writing a low latency server which caches a lot of
static data to be retrieved quickly on each request. 
I have noticed some inconsistent performance with
regards to these retrievals.  In a simple program
where I am simply retrieving an entry from the cache
(no sets) I see performance that ranges from 0ms up to
30ms or more.  I am using the Java client, although I
have used the Ruby client as well to verify my
results.  My questions are:
1. What is causing this varied performance when I am
simply retrieving information from the cache and not
doing any sets?
2. Is there some setting that I can use on the server
or client that might help me get more regular
performance?


Thanks,

Matt
