Re: Linux or FreeBSD a better choice for threads/tasking?

["David C. Hoos, Sr." <david.c.hoos.sr@ada95.com>]

To be fair, the 2.4 kernels before Jan 4, 2001 were not released kernels,
but test kernels.

We've been using the 2.4.1 kernel with a pair of gnat applications, of
which one has 23 threads, and the other 11 threads.

We had been using 2.2.16, but switched because 2.4 kernels
provide a generic SCSI driver which in the 2.2.16 kernel needed to
be replaced with another driver, making that kernel source tree
non-standard.

We found that the 2.4.1 kernel, beside being able to be used in
"standard" source tree form provided improved memory
management, and exhibited no negative attributes relative to 2.2.16.
