Commit Message

Improved adaption in Adaptive W-TinyLFU

When the workload is recency skewed the admission window should be
larger, and smaller when frequency skewed (normal case). Previously
the sampling over benefited the recency by and didn't shrink
promptly when the workload changed. Finding the right tuning is
challenging.

This small tweak seems to do the trick. Running OLTP->P8->OLTP shows
the window is resized quickly and correctly. The result is a higher
hit rate with low cost, as desired.
