Poor network performance on Sam440ep

Hello,

Just wondering if the performance is ok or if something is wrong with my setup.

Transfering 400 MB (in one file) from a PC to my Sam440ep takes 30 min over local network (wired) with Amiga Explorer to RAM:. If I choose my work partition as target (an SSD) it would take 2 hours 11 minutes. Is this performance standard for Sam440ep (533MHz) or should I expect it to be faster? Is network performance faster on a later Sam or X1000?

Regards

Network transfers are greatly slowed down (on all platforms) by SMBFS. Unfortunately, there's little that can be done about it too.

I don't know if Amiga Explorer use smb or some other protocol. Or some private.
But basically, as Rigo said, transfers are slowed by huge protocol on top of TCP / IP - like Samba.

Speed of pure TCP/IP transfer on my Sam440ep 666MHz is:
11130 kB/s = 87 Mbps ( measured by TCPSpeed against fast Windows workstation )

Only solution is to try other protocol. FTP could be faster.
If you will wait week or two, I will test transfer with smbfs on my Sam440. Just now part of my computers and monitors hidden behind Bethelem

Dont think its using SMBFS but TBH dont know. I think I tried running an FTP server on the SAM a couple of years ago but file transfers between PC/Sam where so unreliable - I failed to transfer my MP3 archive of 30 gigs :)

I thought I could fill up a USB stick with files and transfer that way but USB is very slow also.

One idea could be to fill up a HDD with files and transfer directly by hooking it up to the Sam, lets see if it works.

I have a Sam440ep mini-itx 666Mhz (not a flex) and i tried to copy an iso file of about 700Mb from my Macbook pro (mid-2010) with bigsur using smb both on amigaos 4.1 and osx. I copied the file not into the ram because my system has only 512Mb of ram so i copied to my download drawer. I copied the file from the shared folder using the copy and paste function of the workbench and it took about 10 minutes.. I don't know if using Dopus is faster than WB. I have to try..

Update: With Dopus it took about 7:40 seconds..

I use AExplorer between my X1000 and Wondows10 laptop. One thing I did that sped up the transfers was to change the packet size from 1028 to 4096.

On the Amiga side you can change the tooltype. PACKETSIZE=4096
On the PC side you can change it in properties under the Options tab.

This was a long time ago, so I don't know if the default is still 1028 but it's worth checking. It made a huge difference on my system.

Just did a test. It took 1min and 13 sec to copy a 226MB file.

@ktadd Sweet, I will try that!

I think there is something going on with my Sam440 though, occasionally it slows down a lot, like if I chose a file and deletes it, it takes 3-5 seconds just to get the yes/no window to open and while the file is deleted the whole system freezes. Deleting a (a small) file takes 30 seconds when the computer behaves like that.

I have not tracked the problem down, but I think thats why it took so long to transfer the file. If I reboot system it is fast again, however I have not found the trigger that slows it down (and got no clue where to look other than user startup and wbstartup).

@xe1huku
try to change the ram

Thank you, will try if the problem wont go away 👍
