Re: pgbench Comparison of 7.4.7 to 8.0.2

Tom,

Honestly, you've got me. It was either comment from Tom Lane or Josh
that the os is caching the results (I may not be using the right terms
here), so I thought it the database is dropped and recreated, I would
see less of a skew (or variation) in the results. Someone which to comment?
