The notions of "hit" and "miss" are only defined for "basic"
transactions. I suspect your test has a significant portion of
transactions which are not basic. For example, reloads, aborted
transactions, transactions with Range or If-Modified-Since headers,
various HTTP redirects, and CONNECT transactions are _not_ basic.
If you can post the entire generated report or just the corresponding
.lx file (output of polygraph-lx applied to the same set of binary
logs), then I may be able to explain what is going on in terms specific
to your test.
