(In reply to Michael Tuexen from comment #35)
> Is the sysctl output from 14.3 or stable/14?
stable/14
new measurements on original VM (cx11):
(reboot for each re-configuration)
summary:
FreeBSD Offloading Download (CV%) delta % Upload (CV%) delta %
14.3p4 yes 879 (24.21%) 456 (24.21%)
14.3p4 no 902 (13.36%) +2.59% 472 (13.36%) +3.60%
14-087fc6ae0a8c yes 877 (18.19%) -2.73% 476 (18.19%) +0.95%
14-087fc6ae0a8c no 877 (24.66%) -0.02% 404 (24.66%) -15.13%
In general, I would assess results as - these cheap VMs do not provide any
stable results to do such kind of measures, spikes are quite significant
(shared hosting?).
Also, I do not see much correlation on top of FreeBSD version or checksum
offloading.
Also, somehow, download is ~ twice faster than upload, no clue why ...
