I have done a few testings using OpenBSD 4.1 and the original Linux system.
The good news is that I can get about 10MB/s, the sad news is "not with
BSD system". Here are the results of my testings:
*****************************
*** TRANSFER RATE SUMMARY ***
*****************************
slax-5.1.6.iso = 192M
Mac OS X 10.4.9 <-> NetBSD 4.0_BETA2/i386
<- ftp(slax-5.1.6.iso) = 10.23 MB/s
Mac OS X 10.4.9 <-> OpenBSD 4.1/landisk
-> scp(slax-5.1.6.iso) ~ 900 KB/s ; CPU ~ 1.00
-> ftp(slax-5.1.6.iso) = 2.08 MB/s ; CPU ~ 0.94 ; ftp PUT
<- ftp(slax-5.1.6.iso) = 2.27 MB/s ; CPU ~ 0.97 ; ftp GET
NetBSD 4.0_BETA2/i386 <-> OpenBSD 4.1/landisk
-> nfs/cp(slax-5.1.6.iso) ~ 2 MB/s ; CPU ~ 1.86
Mac OS X 10.4.9 <-> PX-EH40L (Linux)
-> ftp(slax-5.1.6.iso) = 8.53 MB/s
<- ftp(slax-5.1.6.iso) = 10.04 MB/s
OpenBSD perfs are about the same than NetBSD's one - except maybe that
OpenBSD seem to keep the CPU charge at 1 (max) during transfer when NetBSD
hits a charge of 3.
Now... where to look to see what happens ?
