I tested on AWS ubuntu 10.04 memcached 1.4.2
When testing with memslap (different concurrent users numbers and different instance types (8G and 1.7G memory)
Top shows 110% cpu on the memcached process and 55% cpu idle in the cpus summary.
What is wrong here?
Is the server using just one core for memcached? If so is it possible to change it to get more out of the box?
