tmpfs

I am running Ubuntu 11.10 desktop on a couple of 8G RAM Wintel boxes. Both have been created automatically by the default installer with a 1.6GB tmpfs /run partition, where I suspect this amount of RAM could be more usefully used elsewhere in the system. I suspect that the installer takes 20% as the default, which is probably OK for boxes with lots less RAM, but seems overkill for an 8GB system. My question is - can I change its size, if so, how, and what are the risks in doing so?

The /run partition does not appear in the /etc/fstab file so it must be set up elsewhere.

/var/log/lastlog gets written to when you log in. The size of this file is based off of the largest UID in the system. The larger the maximum UID, the larger this file is.

MySQL & tmpfs : performance

as seen on Server Fault - Search for 'Server Fault'
I was wondering if, and how much, using tmpfs could improve MySQL performance and how it should be done ? My guess would be to do mount -t tmpfs -o size=256M /path/to/mysql/data/DatabaseName, and to use the database normally but maybe I'm wrong (I'm using MyISAM tables only). Will a hourly rsync… >>> More
