Well, I personally will still be curious how much does SMP affect the
case of one worker and one or more diskers...

I do not understand why you are asking this question in AUFS context.
AUFS does not use diskers!
because it's diskers (rock store) who switch to SMP mode when "workers 1" is
used, and this may cause troubles to *ufs.
Today, only Rock store uses diskers (in SMP
mode). Some other [ufs-based] cache stores use various helper threads
and processes for I/O as well, but those helper processes are not
diskers or even kids in SMP terminology.
this is something I'd like to understand better...
do diskers only provide I/O to the requestor?
Diskers primary function is low-level disk cache I/O. Like all kids,
diskers respond to cache manager requests and Squid management events
(e.g. shutdown and reconfiguration). IIRC, diskers also build in-RAM
cache_dir index.

their own or also the shared one?
