Comparison of linux and freebsd kernels?

Question

linux

I came across this work comparing Linux kernels (2.6.24) and Fryakhi (7.1)
www.cs.virginia.edu/ ~kc5dm/projects/osperf.pdf
================ =======
We determine that FreeBSD performs equally or
better than Linux on file read operation, page allocation latency and page touch latency measurements. We
also find out that kernel call overhead is more in
FreeBSD than in Linux. Also, context switch delay is
more uniform in FreeBSD than in Linux, while signals
perform faster on Linux than on FreeBSD.
=======================
Actually the question is, what has changed in this regard since that time and how relevant is this information for current upstream kernels?

Answer 1

openbenchmarking.org/result/1112113-AR-ORACLELIN37

Answer 2

Phoronix has a bunch of tests .

Answer 3

The topic is the whole I \ O topic is open, but it would be interesting to look at a bunch of LVM + linux-favourite-fs and ZFS v28 (or not too old)

Answer 4

As for free, core 8 has changed quite a lot compared to 7, generally for the better, but there are some points in the network part that have worsened. I think the info can be considered not relevant - frya 9 is on the way, we need to test everything again;)

Answer 5

FreeBSD had a very stable version 4.
Very.
In version 5, they started cutting multiprocessor and broke everything (performance, stability). Which, in particular, led to the spinoff of DragonFlyBSD, built on the basis of 4, but with a different multiprocessor.
In version 6, multiprocessing was fixed.
In version 7, single-processority was fixed.
I would not look at such ancient versions.
