We were seeing very high compilations and recompilations on a server to the point that it started causing us some very serious issues (admittedly this wasn't the sole issue but it was certainly a contributing factor, the other factors were also very interesting so I might look...

The other day I got thinking about what would happen if all databases on a single instance grew out, every single one of them! but not just once, what if they all grew out three, four or fives times overnight - what would things look like? Well I know the likelihood may be slim but... Continue Reading →
