ahagge, thanks for you info.
Can you test some ftpd performance? like proftpd, pure-ftpd

OK, you asked for it...all tests below used ProFTPD on the Linkstation. Completely stock install, no tuning.

I happened to be in Windoze at the time I read your request, so here's some timings using the Filezilla client (MTU of 1500 on the PC):

  • FTP put (PC->Linkstation):
    Code:
    914,763,843 bytes, 2:45, 5.3 MB/sec
  • FTP get (Linkstation->PC):
    Code:
    914,763,843 bytes, 0:51, 17.1 MB/sec
I rebooted into Linux (MTU of 9004) and tried some command-line FTP:

  • FTP put (PC->Linkstation):
    Code:
    ftp> put 1GBtestfile
    local: 1GBtestfile remote: 1GBtestfile
    227 Entering Passive Mode (192,168,0,200,160,173).
    150 Opening BINARY mode data connection for 1GBtestfile
    226 Transfer complete                                 
    912909312 bytes sent in 65.9 secs (13860.40 Kbytes/sec)
  • FTP get (Linkstation->PC):
    Code:
    ftp> get 1GBtestfile                                    
    local: 1GBtestfile remote: 1GBtestfile                 
    227 Entering Passive Mode (192,168,0,200,201,170).     
    150 Opening BINARY mode data connection for 1GBtestfile (912909312 bytes)
    226 Transfer complete                                                   
    912909312 bytes received in 19.2 secs (47636.84 Kbytes/sec)             

Yeah, I couldn't believe my eyes either. Some kind of caching, I thought. So I tried again with a 5 GB movie file and 4 GB movie file:

Code:
ftp> get test.vob                                                                                                                         
local: test.vob remote: test.vob                                                                                                       
227 Entering Passive Mode (192,168,0,200,143,167).                                                                                         
150 Opening BINARY mode data connection for test.vob (5451474944 bytes)                                                                   
226 Transfer complete                                                                                                                       
5451474944 bytes received in 119 secs (45908.74 Kbytes/sec)
ftp> get test2.vob
local: test2.vob remote: test2.vob
227 Entering Passive Mode (192,168,0,200,227,78).
150 Opening BINARY mode data connection for test2.vob (4346652672 bytes)
226 Transfer complete
4346652672 bytes received in 87.1 secs (49928.62 Kbytes/sec)

So it's for real...almost 50 MB/sec. from the Linkstation to the PC using FTP... :shock:

Edit: This was done with a self-compiled 2.6.28.5 kernel with preemption OFF.

WOW! AMAZING!

Now that the disk I/O becomes the bottleneck.

Thanks again, ahagge, for your info.

I will test it myself again with preemption off to see if it helps.

OK,

seems that the smb Performance Problems are history.....

Have u made some changes on your smb.conf? Or on your clients?

And how is the performance with standard mtu settings?

Which Kernel do you use for compiling? Original from kernel.org or from orion git?

And please, can you post your kernel config?

I tried with my own kernel from orion git sources (2.6.29-r5). No Jumbo-Frames, and i got aprox 15Mb/s Read-speed and aprox 12.5Mb/s Write-Speed.

But my Kernel is big. 2Mb

My goal is a small kernel, with the only need of functions.

greetz,

Bitspyer
