font-family:Arial'>I am trying to use memcached to cache some database lookups,
and everything is fine, except every so often, like every twenty hits, I get a
hiccup. Where nineteen of the hits take like 0.000425100326538086
seconds, and the twentieth hit takes 1.04001402854919 seconds. Every
hiccup I have seen has taken 1.04 something seconds. Is there something
that memcached does occasionally to catch up or the like that would take around
a second on a dual xeon 2.80GHz box? I am using the perl interface and the
call I am doing looks like this<o:p></o:p></span></font></p>
