I have a similar problem on this one. The reason for this is my application performs back to back updates. And, as came out of my performance tests, the update immediately after the first one, seems to be a lot slower than as compared to not having any update logs.
Is this a genuine case, or did I miss something in my performance tests ? Any pointers on this one are highly appreciated.
