Great news! Since things are now beginning to get to the usefully
runnable stage, could you (without investing too much time) answer two
questions:
(1) Do we have any experience getting KSE up and running on SMP hosts?
In the past this has been a sticking point for KSE, and recently there
have been problems for libthr as well. Give the threading goals of
(a) improved I/O latency, and (b) parallelism to see an improvement
over libc_r, SMP support is an important thing to know works, or is
close to working. Do you guys have the hardware you need to do that
testing?
(2) Do we have any early performance measurements (quantitative or
otherwise) the compare for gains/losses vs. libc_r for libpthread?
I.e., comparison of context switch times, throughput for some pthread
application we like (dumb mysql test), etc?
Also, any luck getting KSE context management support up and running on
non-i386?
