Sorry.
I'd like to be kind, but I confess I am not good enough to get these
right now

What I see is that, for sure, with BWcache, you need a lot of RAM,
especially if you have two or more Virtual host running different copies
of phplib

The full blown phplib, with user,auth (yes, default_auth, that is
everywhere), horde, as major libraries, is included in everywhere,

I see that each httpd child starts 2.7M.
Then, when supposedly the loadable php module and others are requested,
and once every child has had the phplib libraries compiled (I see it
from the log, because at first requests, for each child, I get all
'cache compiled, after a while it's all 'cache-hit'), each child gets to
around 12 M, where it settles.

APC is more sofisticate with memory, as it keeps one copy for all apache
childs. in BWare every child has it's own cache of compiled php stuff,
whuch get compiled at the very first request.

The speed is impressingly, visibly much much faster. Cannot say more.
