ZFS Performance

A great post here from Yves Trudeau,  who is one of the the top database tuning experts in the world today.   A previous company I worked for hired Yves (via his company, Percona) to help with some DB issues and I was fortunate to spend a couple of days with him.   A very cool and interesting guy.  He is a martial arts practitioner as well and gave me some tips on getting started.  Yves is from the Montreal area so I thought a French language video might be apropos for this post  🙂
