Hello,
I was wondering if the "Thundering Herd"
(http://www.citi.umich.edu/projects/linux-scalability/reports/accept.html=
)
problem exists in FreeBSD 4.1-Stable?
I have a bunch of processes doing an accept on the same fifo at the
same time. I tried serializing the accepts using flock, and it works
most of the time, but it seems that I hit a race condition once in a
great while when trying to get a lock.
I tried the same code without serializing the accepts, and it works,
but I was just wondering how well it will scale. Thus the 'Thundering
Herd' question.
Any pointers/RTFM/anything welcome.
P.S. The code is written in Perl 5.005_03 if that matters.
