optimal deployment of memcached

[Shayan Ghazizadeh]

Hi everybody,

In multiple presentations I have seen Brad talk about running multiple  
instances of memcached on "high-end" boxes. I was wondering what are  
the benefits of doing so?

We have two boxes with 12G of RAM and 8 processors each that host our  
memcache cluster running one instance of 64bit memcached. Is this a  
good idea? should we instead run multiple instances on each? what are  
the pro/cons?

Thanks,
Shayan
