juju 1.17.0 + mysql / HP > 2G

[Jason Robinson]

Hi,

anyone will use mysql for. Juju's memory usage has changed quite a
bit. We have seen the mysql state errors change from rare or very
common.

How much more memory does a server running MySQL with Juju use compared 
to a vanilla Ubuntu server running MySQL?

I'm kind of worried hearing "2G is small" - I maintain production 
servers with less memory for small sites. Especially as Juju encourages 
running a single service on a single machine - running more small 
machines and less large ones seems to me a thing it encourages.

Thanks :)

Br,
Jason
