BRAINSTORMING NEEDED: Memcached Slowing Machine

[Steven Grimm]

When the machine slows down, how much free physical memory does the 
machine have? Is the entire memcached process memory-resident, or has 
the OS started to swap it out? The instant memcached starts having to 
swap, its performance plummets. The behavior you describe is consistent 
with a memcached instance growing larger than the available physical 
memory over time. When you restart it, it would start small again and 
not need to swap.
