Scott, I'm quite aware of what noatime does ... you didn't miss a post, but if you look at Mark's graphs on http://wiki.postgresql.org/wiki/HP_ProLiant_DL380_G5_Tuning_Guide they pretty much all indicate that (unless I completely misinterpret the meaning and purpose of the labels), independent of the file-system, using noatime slows read/writes down (on average). -- Please don't top post, and don't use HTML e-Mail :} Make your quotes concise. http://www.american.edu/econ/notes/htmlmail.htm
