If you follow the bug report, you might notice that this is probably an issue of socket flags. I know that *BSD and Linux handle sockets slightly differently, but that about covers my knowledge of these things. Maybe a solution can be found simply by setting the right flags for the socket...
Any ideas in this line of thought? I am kind of afraid to approach the Perl guys with this issue, although it might be worth a try... Hm, I fear buffers don't help me at all. You see, I wish to send thousands of very small tcp packets to the server in as little time as possible. Thats where the program running under OS X outperforms the Linux version by several orders of magnitude. This is what suggests that the problem could be lying in the difference between BSD and Linux sockets. OT: How would you think pypy could help, if this is OS related?
