RE: Bind variable peeking and Dynamic sampling

Yes, Tanel has been kind enough to share some of his secrets with me. He actually posted a preview of his presentation on this list a few months ago as well. I am currently looking into implementing his methods, but still have some testing to do.  

I have actually tried disabling bind variable peeking also, but got negative results immediately as the first query I tried (the same one I was having trouble with due to inappropriate plan sharing) suffered a major drop in performance - running in 20 seconds with the bind variable peeking compared to 20 minutes with the plan it chose w/o peeking at the binds.  

Thanks,
Brandon

To ALWAY_PEEK is to parse always, right?
