IO, IO, It's Off to Tune We Go
If I were a betting man, I would wager your disk IO system is probably the biggest bottleneck in your SQL Server right now. Sure, there are lots of moving pieces, but if you can tame the IO situation, you are putting yourself in the drivers seat. So how do you go about putting together the pieces you need to identify your IO constraints?
I chatted with Theresa Iserman, a Premier Field Engineer at Microsoft about some of her thoughts and why IO in general is an issue. She gives us some guidelines and even some metrics to check out. Join us in the conversation, and I’ll see you on the SQL trail . . .
