The best Zorro slot network card

[Effy]

I definitely have had transfers over 150 kb/s depending on which site I was on, never had any complaints of any kind. CDroms work just fine on the IDE connector. Didn´t try the other expansion ports though. Anyway, I got one for sale on Ebay if anyone is interested !! Check out this thread  :-)

I, myself have an Ariadne II network card.

It's using Realtek's RTL8019AS chip which has an ISA bus interface.

I use smbfs to access my server. i did some performance tests with SysSpeed to see what transfer speed I could get with different configurations.

What I found out was that how much I did overclock the system maximum transfer rate seemed to be the following.
Write: 230 kbyte/s
Read: 690 kbyte/s

Apparently this seems to be more a limitation of smbfs than the network card since tcpspeed still gets a performance boost. (Maybe something with interrupt timings!?)

Oh, by the way I succeded to improve the the benchmark values for opening files by replacing the 25MHz oscillator on the Ariadne II board with a 50Mhz variant. This didn't increase the heat on the board. (I expected that the Realtek chip could operate beyond it's specs without problem and it did)

Here is an article (in italian), that has some benchmarks for the x-surf:

AmigaExplorer 3 (configurato con packet size di 16384)

da Amiga a PC:  154 KB/s

da PC a Amiga:  210 KB/s



FTP (wu.ftp su Amiga e ftp da finestra DOS su PC)

da Amiga a PC:  380 KB/s

da PC a Amiga:  255 KB/s



Samba (condivisione file su PC e smbclient su Amiga)

da Amiga a PC:  144 KB/s

da PC a Amiga:  160 KB/s

Just to mention from the same article, that the same ISA card (of the X-surf) used on a PC can go up to  1 MB/sec, but on the AMiGA side hardly beats half the speed... This might be due to the ISA -> Zorro conversion?

Are there no benchmarks using a simple software, downloading a file from a pc connected with a crossover cable using HTTP, preferrably to the ram-disk?

The reasons for this are:
1. Ftp is a cpu-blog.
2. Samba is a larger cpu-blog.
3. From the results, amiga explorer seems to be a cpu-blog too.
4. A piece of good written software retrieving files using the HTTP-protocol will use little cpu power.
4. Most new 100Mbit switches doesnt handle 10MBit NICs that well, thats why a crossover cable should be used when benchmarking.
5. With the ram-disk you are not affected by software which uses the filesystem in an inappropriate way for fast transfers.


After all, it is the performance of the NIC you want to try to measure, not the performance of your CPUs, right? Then it is a very good idea to try to minimize the CPU-usage!
