Squid request response time for slow clients? Squid request response time
with fast clients? Squid disk response time for hits? Squid disk response
time for cachable misses? Squid disk space usage? Squid memory usage?

In other words, what is the metric you are optimizing and how will 4KB pages
affect it? In most cases, there will be a tradeoff. It is not 100% obvious
[to me] that 8KB disk page is worse in all respects... Please specify the
metric or explain why 8KB pages are worse for everything we do.
