Here are some figure for the Blackdog:
System Laptop Blackdog
CPU Pentium M PowerPC 400 (Virtex-II Pro)
Freq 1.73 Ghz 384 Mhz
Bogomips 1598 380
Cache 2048 KB ?
Mem 1Go 64Mo
Kernel 2.6.13 2.6.10
OTP R10B-6 R10B-8
ackerman(3,11) 8s 89s
I do not know what your cheap-concurrency test is doing, but if you send
it to me I can launch it for a comparison. I have been doing some
concurrency test and manage to create 10000 thousands process in 173
microseconds and message passing took in average 15 microseconds.
Cheers,
