Hi Michael,
With UTF2 you mean "Uno Threading Framework 2"? I can see how it helps
the performance if we reduce mutex locking (especially Solar-Mutex, of
course) but naively I would assume that reference counter as programming
concept are mostly independent from that effort? Does UTF2 significantly
reduce the amount of reference counter usage? How?

Actually, yes. I'm glad to hear that we have a better implementation.
If we can avoid locking as much as possible. UTF2 should help in this
regard.

Hi Michael,
slightly off topic, but speaking of performance improvements: Didn't
these numbers about the expense of the reference counters on older
Intel
processors (pre Hyperthreading, say Pentium III) come initially form
you?
I changed the implementation of the reference counters in m191 so on
older processors should we see 5-6 percent improvements on the more
notorious docs while hopefully not damaging the performance for current
CPU's.
