From: live.fx on 15 Mar 2010 05:20 also test with connection between another linux node and server: LinuxNode02 -> Server : NFS LinuxNode02:~ # time cp -v /4GB_test.file /Server/Projects/ `/4GB_test.file' -> `/Server/Projects/4GB_test.file' real 0m59.831s user 0m0.120s sys 0m7.692s approx.speed = 69.4 MB/sec ----------- Same server same file but trough SMB: LinuxNode02 -> Server : SMB LinuxNode02 :~ # time cp -v /4GB_test.file /mnt/Server/ `/4GB_test.file' -> `/mnt/Server/4GB_test.file' real 2m58.724s user 0m0.072s sys 0m16.889s approx.speed = 22.8 MB/sec ------------- Same server and client. Same file. Same disk - RAID5. Same OS, but transfer to SAMBA is very slow. What can i do ? Of course i try to setup samba on another computer and start to test it: LinuxNode02:~ # time cp -v /4GB_test.file /mnt/Server2/test/4GB_test.file `/4GB_test.file' -> `/mnt/Server2/test/4GB_test.file' real 2m42.480s user 0m0.108s sys 0m17.373s approx.speed = 25.8 MB/sec ======= Another server, same speed, just a little bit faster. I think this because Server2 - 8core Xeon, 8 Gb RAM, and 3 sata2 HDD - XFS filesystems. SAMBA speed is very very slower instead of FTP and NFS. What solutions, or where i can find it? May be some standard benchmarks? Can SAMBA transfer files faster than 25 MB/sec ? Someone have this transfer speed with SAMBA ? -- View this message in context: http://old.nabble.com/Samba-3.5-slow.-Help-with-benchmarks-%21-tp27894473p27901821.html Sent from the Samba - General mailing list archive at Nabble.com. -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
From: Jim Salter on 15 Mar 2010 15:00 I get about 51MB/sec over my gigabit LAN, serving from Samba 3.4.0 on Ubuntu Karmic amd64 to smbclient 3.3.6 on FreeBSD 7.3-R amd64. 5tb# smbclient -I 192.168.0.20 -U user //192.168.0.20/share -c "get 1G.bin" Enter user's password: Domain=[BANSHEE] OS=[Unix] Server=[Samba 3.4.0] getting file \1G.bin of size 1073741824 as 1G.bin (50717.1 kb/s) (average 50717.1 kb/s) For comparison, the same transfer gets 54.8 MB/sec by FTP (using pure-ftpd on the Ubuntu Karmic machine and wget on the FreeBSD 7.2-R machine). CIFS is a lot heavier than FTP, so this probably represents "as good as it's going to get" on this particular network. (And your gigabit network may very well be faster than mine - mine's all cheap off-the-shelf SOHO parts.) > > Miguel Medalha wrote: > >> >>> Can you show me, how yours SAMBA work in Gigabit LAN ?

Today i found 2 PC-s in this chaotic LAN, they do transfer speeds from 50 MB/sec (in both directions) and one Windows 7 machine with 80-100 MB/s. This fact removes all claim from SAMBA server.
