Yup I have that enabled. > These two are not memory related. Perhaps you were thinking of > maximum_object_size_in_memory?

Hmm ok, it's possible I have totalled the number of READ system calls incorrectly. Because of the large numbers of READs I was assuming that a TCP_IMS_HIT was _always_ from a check made against a file on disk and not from memory. As you confirm that TCP_IMS_HITs can come from either memory or disk I will check my totals again. Thanks for the confirmation. -- Michael Pye
