I dont think your validation algorithm is doing anything at all right
now. The actual validation procedure is to open every disk object and
verify the details of its existence and size. That takes a relatively
long time and is only performed if you start Squid with the -F command
line option. Otherwise it is only performed as-needed by live traffic
(TCP_SWAPFAIL_MISS gets logged if live validation fails).

The 1 difference is a bit odd though.
