Nice metaphor... I have insane number of trying, with all possible switches
combinations and no luck.
I want to see good SAMBA speed testing results, if this possible.
===============
What results i have today:
1. iperf test between Linux client and Server:
linuxnode1:~ # iperf -c Server -p 5001 -fm
------------------------------------------------------------
Client connecting to Server, TCP port 5001
TCP window size: 0.02 MByte (default)
------------------------------------------------------------
[ 3] local 192.168.0.34 port 49825 connected with 192.168.0.210 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 1125 MBytes 943 Mbits/sec
linuxnode1:~ # iperf -c Server -p 5001 -fm
------------------------------------------------------------
Client connecting to Server, TCP port 5001
TCP window size: 0.02 MByte (default)
------------------------------------------------------------
[ 3] local 192.168.0.34 port 49828 connected with 192.168.0.210 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 1125 MBytes 943 Mbits/sec
2. Copying 4GB file with SMB, NFS, and FTP to Server: ATTENTION - this
copying from linux, who mount Server trough CIFS. Test with windows copying
show different results - slower.
Copying to SMB share:
linuxnode1:~ # time cp /4GB_test.file /mnt/Server/
real 2m36.703s
user 0m0.079s
sys 0m11.794s
Copying to NFS share:
linuxnode1:~ # time cp /4GB_test.file /Server/Projects/
real 4m28.546s
user 0m0.180s
sys 0m30.209s
linuxnode1:/ # time cp -v /4GB_test.file /WinClient1/In_Out_Box/
`/4GB_test.file' -> `/WinClient1/In_Out_Box/4GB_test.file'
real 2m19.588s
user 0m0.077s
sys 0m8.274s
linuxnode1:/ #time scp /4GB_test.file user at Server:/mnt/RAID/Projects
Password:
4GB_test.file
100% 4096MB 58.5MB/s 01:10
real 1m12.289s
user 0m49.811s
sys 0m8.542s
===================================
Question.
What points, configs can i check, for getting faster SAMBA ?
And my primary question: Can SAMBA connections be fast like "Windows ->
Windows" connections ? Or i try to get something unreal ?
If yes - next questions:
1. SAMBA speed is depend from kernel or OS or both ? I use kernel
2.6.31.12-0.1-desktop, and OS=openSUSE 11.2 x86.
2. What difference between copying big files to SMB share and small ?
Very Many Thanks for answers..
