Hello everybody.
I know that speed does not matter this days, and security matter.
But i want an advice, i have xeon computer with fresh disks, they work
pretty fast,
and also i have 1 gbit switch and 1gbit intel nic on both side, here
is iperf test:
$ doas iperf -s
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 16.0 KByte (default)
------------------------------------------------------------
[ 4] local 192.168.0.1 port 5001 connected with 192.168.0.77 port
57972
[ ID] Interval Transfer Bandwidth
[ 4] 0.0-10.0 sec 1.04 GBytes 893 bits/sec
but when i try to upload something via samba or ftp speed is slower :(
the fastest speed i have is between linux and openbsd ftp server,
speed reaches 85 MBytes/sec
samba between linux and openbsd is 45 Mbytes/sec
I also have old imac with core2duo, and network perfomance between
linux and mac is faster, i can achieve speeds of 110-115 mbytes/sec.
I have not tried to tweak speed somehow, so this is default system
perfomance.
Is there any chance to speed up my networking?
Thanks!
I think you are confusing various units here. The unit you really care
about here is Mebibytes per second. A one gigabit nic can transmit data
at a theoretical maximum speed on 1000 Megabits / 125 Megabytes / 119
Mebibytes per second. You also have to take into consideration various
other slowdowns. The more complex the protocol, the slower the transfer.
85 MB/sec sounds about right for ftp in my opinion, samba may need some
performance tuning.
