ASUS RT-AC1200GU SAMBA slow transfer speed

[samba4linux]

My ASUS RT-AC1200GU WLAN router has USB2.0 interface for an external storage. The transfer speed over SAMBA to / from that router is ~7MBps on a Gigabit connection.


# Details

Setup: hard drive has NTFS partition, connected to WLAN router. Linux PC1 is connected to router on LAN port 1. No other connections.

The router is using latest firmware from the manufacturer (3.0.0.4.380_10732)

# Tests

For comparison, a SAMBA server has been installed on the PC. File transfer speeds from PC1 (linux) to PC2 (win10), connected over the router using LAN, reach 90+ MBps.

# SAMBA configurations

configurations on PC1:

testparm:
Load smb config files from /etc/samba/smb.conf
Loaded services file OK.
Server role: ROLE_STANDALONE

do I have to change configurations on the router or PC? Is there anything I can change?

any help is much appreciated, thank you.

You wont get more on router-USB (its not a NAS), EXT might be faster than NTFS but far from samba-server on your PC.

Truth be told, I never worked with SAMBA before so I don't know anything about it. My naive self assumed a bottleneck on the USB2 interface. A bottleneck on USB2 should be a bit closer to 27MBps for large files.

This router in particular does not support EXT, unfortunately. I didn't try FAT32. I'll try a memory stick to see if it makes any difference.

 

[samba4linux]

I cannot observe any difference in speed using FAT32, or other drives. What are the speeds I can expect from SAMBA?

 

[FTC]

That router has just 128MB and a 880Mhz processor and a single USB2 port. Too low specs for samba to run correctly on nowadays big disks. I definetly would go for a real NAS or change the router to a much more powerful one. For instance the RT-AX88U does reach 115MB/sec samba transfer speeds, but this router has 1GB and a quad core 1.8Mhz processor ... it is much more expensive though..

Thank you this is really great info. where do you look up this information? Because I might still be able to return this device and the store has RT-AC1750U and RT-AC1900U in stock. ASUS product sites don't specify RAM or CPU

I hooked up a Raspberry Pi as SAMBA server now and get 9.4MBps. The Paspberry Pi has a fast ethernet connection!

the slow SAMBA is not essential, but it bugs me a little...

 

[samba4linux]

never mind, I found it. I wish I knew that before...

thank you for your help

Hi, the specs for routers you can find them searching in google for 'rotername wiki'. Re. The throughput figures I have are for my own experience with a RT-AX88 and a RT-AC3200 I had overclocked to 1.4Ghz (which could reach 55MB/s and was still much more powerful than the 1200).
