I noticed: <http://norloff.org/ntp/shm-test/>
SHM test for windows?
Yes and no:
This is testcode that verified the possibility of handling 100k to 1M
shared memory messages per second, without using any kind of OS locking
primitives. The key idea is to use a msg array in round robin fashion,
each msg aligned and sized so that it uses one or more separate cache lines.
It has _not_ been integrated into ntpd, it would require a new sub-mode
for the SHM driver.
