Ariadne slooooow

[orange]

I've just bought Ariadne card. :banana:

But its very slow  :-(
(using it on A4000 CSMKII '060, PIV, WB3.5 with Miami&smbfs)
I get only 13 Kbytes/sec when transferring Amiga->PC
even parallel cable would be faster..

and 150Kbytes/s PC->Amiga, which is very nice still not 10MBps, but good. IIRC, A1200 ('030) with 3COM PCMCIA had about 200Kbytes/sec.

I know there is no chance to get full 10MBps, but theres gotta be some way to get more, right?
What should I check first?

ariadne.device is v1.50

[Castellen]

I have a similar setup with an Ariadne and get approx 200 kb/sec when doing transfers using SMBFS.

Using ariadne.device 1.44 with MiamiDX.

Have you tried using FTP instead to test the hardware and drivers properly?  FTP is faster as it doesn't have as many protocol overheads.

Also check you have the latest SMBFS, which is ver 1.63.

And also try SMBFS connecting to an Amiga running Samba, or a different PC.

latest version is actually 1.66. I've switched to your 1.63 and now upload is ~70Kbytes/sec, great :banana:

thanks.. :-)

@orange:

Try to get hold of AmiTCP/Genesis instead of Miami as it is a much faster TCP/IP stack.

Also when measuring speed you should remove as much protocol overhead as possible. A good tool for that is ttcp which measures the speed when sending/recieving raw tcp/udp packets. This will show you what speed the combination of your computer, network card and TCP/IP stack can manage without the added protocol overhead of for example ftp or samba. In other words it will give you a good estimate of how fast a TCP/IP-application can communicate at be as best on your system.

Amiga version of ttcp
Windows version of ttcp
Sourcecode for ttcp

---- Quick guide for how to use ttcp ----

- I will use amigaip instead of your Amigas ip-address and pcip instead of your pcs ip-address.

- I assume that you have installed ttcp in your path and that the executable for it is named 'ttcp'.

- You shall run ttcp from a shell/cli/command-prompt on both the Amiga and pc.

- I will call the shell/cli/command-prompt on both the Amiga and pc shell.

- I assume that your pc is fast enough to not have a negative impact on the results. A Pentium with a PCI network card should be fast enough.

Below I will describe what to input in the shell and the order of it on the Amiga and pc.

To test the speed when sending tcp-packets from your Amiga to your pc:
1. PC: 'ttcp -s -r'
2. Amiga 'ttcp -s -t pcip'

To test the speed when sending tcp-packets from your pc to your Amiga:
1. Amiga: 'ttcp -s -r'
2. PC: 'ttcp -s -t amigaip'

To test the speed when sending udp-packets from your Amiga to your pc:
1. PC: 'ttcp -u -s -r'
2. Amiga 'ttcp -u -s -t pcip'

To test the speed when sending udp-packets from your pc to your Amiga:
How to make this test is only included for reference. It will most likely not work as the protocol used - udp just sends packets as fast as possible without checking if it was recieved correctly. This in combination with the Amiga not being able to recieve packets as fast as the computer in the other end is sending them which usually is linespeed (100MBit in your case?) makes this test fail. Usually the Amiga doesnt even understand the test is done because it havent recieved all the packets sent by the pc and the pc reports speeds of over 10MByte/Sec.
1. Amiga: 'ttcp -u -s -r'
2. PC: 'ttcp -u -s -t amigaip'

thanks,

here is what i got (copy/paste from PC DOS, Amiga shell is slightly different):

Sorry if this sounds silly, but can that UDP thingy be used for transferring files since its a lot faster than tcp?

@orange:

Comments on your results:
Amiga -> PC, TCP:
This result way to low considering your machine specs. I noticed that you are using the Miami TCP/IP stack which is very slow compared to AmiTCP/Genesis, but still it seems unreasonably slow. I will include results from my Amiga with 060 and Ariadne using AmiTCP/Genesis.

PC -> Amiga, TCP:
Make sure you always start the ttcp on the recieving end first - in this case on the Amiga.

Amiga -> PC, UDP:
This looks just about right using the Ariadne Sana2 device. You just cant seem to send UDP-packets faster for some wierd reason. You will also see that I didn't get any better results in this test on my system using AmiTCP/Genesis either. The wierd thing is that I get about double the speed when sending TCP packets instead which doesn't make too much sense as TCP packets requires more cpu. Also if I repeat this test with an A2065 (similar card, the same network chipset) I get the expected results - better when sending UDP packets than TCP packets, so it seems like it is connected with the Ariadne Sana2 device.

PC -> Amiga, UDP:
Now I am repeating myself from the end of the last post quite some, but anyhow.. This result will just show how fast your pc can send packets to the buffers in your switch. This as when sending packets with the UDP protocol, they are just sent as fast as possible without checking if they were recieved correctly. This in combination with the Amiga not being able to recieve packets as fast as the computer in the other end is sending them which usually is linespeed (100MBit in your case?) makes this test fail. Usually the Amiga doesnt even understand the test is done because it havent recieved all the packets sent by the pc and the pc reports speeds of around 10MByte/Sec (if you have a 100Mbit switch).

UDP doesn't check if the packets were received correctly, this is why it is faster. You would risk to lose data if you'd send files with this protocol.

I got results from PC->Amiga, the problem was that MiamiDX FIREWALL was ON! (and I forgot to check it, duh)
Here are the results:

D:\utils>ttcpw -s -t 10.1.92.197
ttcp-t: buflen=8192, nbuf=2048, align=16384/0, port=5001  tcp  -> 10.1.92.197

ttcp-t:

It seems to affect Amiga2PC speed, too!!!! :-o  :-o
I got now  (Amiga->PC) WITHOUT FIREWALL:

ttcp-r:

smbfs gives me ~220 Kbytes/sec woow

yessss "..speed, gimme what i need.."
 :hat:


BTW, I've turned off SOCKS,  maybe that was important too.

[patrik]

@orange:

Great news! Very reasonable too as firewalling adds a lot of overhead.

If you want even more speed - get hold of AmiTCP/Genesis.

Dump Miami and go for AmiTCP or Genesis instead! They're much faster than Miami!
