Hi
I see you have got
There are no rules. Google's servers are typically two cores with 4GB. They
prefer numbers to iron per server.
One can always trade cache for CPU and disk IO.
On one of my servers, query_cache_size= 256M, eliminated prunes and
got me an 8:1 hit to insert ratio. You might experiment to fin

Are there any rules of thumb or formulae for a good performant RAM
size (per core?) for a busy data base server, mySQL is the database
in question. In this scena

Michael,
Stick to the default swap like Jim recommended. It is
always a good idea to have swap, even though you may never use it.

No. A modest amount of swap may permit the OS to work itself out of memory
contention. A large amount of swap permits the OS to dig itself into deeper

The defaults are rarely an issue. On one server of mine:

Hello All,
My name is Michael,
I have a new Dell Server that I am about to install Ubuntu 9.04 Server
AMD64 onto. I have 4 GB's of RAM. My question? Is there any need for a
SWAP partition with 4GB's of RAM?
Thanks,
Michael
