Which bzr branch? To test Large Rock support, you should be using
https://code.launchpad.net/~measurement-factory/squid/collapsed-fwd

Why do you want to increase the slot size? The 32KB slot size limit does
not limit the size of the responses that Large Rock can store. It comes
from shared memory-related limits unrelated to caching. In most cases,
you should not specify the slot size to let Squid pick the "best" one.

Any potentially related warnings or errors in cache.log? What does cache
manager mgr:storedir page say before and after that "hit 0%" happens?
How do you know that Squid is not writing anything to disk?

The first one is a misconfiguration -- we should document and handle it
better than assert, but other than that, it is not a real problem. As
for the second problem, I have not seen Squid stopping disk I/O after
hours (and days) of use. More information is needed to troubleshoot it.

HTH,

P.S. I disagree that these questions should be posted to squid-dev
(because they are not related to Squid development) and recommend that
you continue this thread on squid-users. Your call which mailing list to
use, but please pick one and stick with it.
