Re: memcached slower than file IO

If you are using the same file in every request your OS is probably using a cached copy in memory. It won't hit the disk every time. While memcached does store everything in memory which is fast, it transmits data over a socket which is slow. You are really comparing using local memory vs. using memory on a different machine. I use memcached to reduce hits to my database which is much slower than memcached. Sometimes I also use it to store objects that are expensive to create. This is just a trade off between CPU and network access. -- David blog: http://www.traceback.org twitter: http://twitter.com/dstanek

This script will not run multiple memcached requests in parallel. Is
that what you were going for?

Re: Memcache serving 24gig a node?
Spreading across more boxes also makes you more fault tolerant. If one or two go down your database (or other expensive resource) would still be OK.
