Consider enabling query cache in the database instead. In terms of
disk operations, it's going to be the same or faster (reading from
the DB vs. reading from a file where session information is stored);
in terms of CPU time, much easier (no serialization/unserialization
required).

Yes. Opcode caching. PHP can be configured to cache the
intermediate
bytecode, so it doesn't have to go back to the source files, unless
they have been modified.

Most likely.
