Crossover network speed transfer problem

[DiegoZuneda]

Hi, all!!



I have two computers,
500 MHZ Celeron W98 128 MB RAM
1.0 GHZ ATHLON W98 512 MB RAM
Both are with the same network card 10/100 Zaapa with a crossover cable cat 5, when I transfer files from ATHLON to CELERON, all it's OK, but when I transfer files from CELERON to ATHLON, the speed transfer is very...very slow....for example, a 130 MB file can take ~2 Minutes in the first case, and 71 Minutes!! in the second case.....

I've tried to change the network cards with a 3Com 10/100 and am Intel 10/100, with the same slowly results....

Anyone have any idea about this?

Thanks a lot!!!

Diego

Well on the surface the Celeron probably has a lot slower bus speed of the processor, and a smaller cache also. The Athlon probably has twice the bus speed and twice the cache size.

If this is a PII level celeron, the PII processor cache memory only runs at half the speed of the processor???? This is where the AMD K7 out ran the PII due to the memory Cache speed.

I would try to use the Athlon as a File server and download files to it instead of the celeron. It might be time to upgrade the 500 Celeron. The prices are probably pretty low on 1.2 Gig Celeron Processors and motherboards. Prices might drop again around Xmas time if Intel comes out with a 3.0 Gig Processor before the end of the year.

Another idea is to look at the speed of the hard drives. Does the celeron have a 5,400rpm or a 7,200rpm drive. Also check the DMA settings in the BIOS to make sure they are maximized. Sometimes the network settings can be adjusted also. You may want to check both of their network settings for possible differences. What is the preferred networking protocol? I have heard it might be possible to change the packet size in the windows registry if that is a problem. If you do not like my post feel free to point out your opinion or my errors.

Also just double check to make sure that the destination folder is shared and that your files will have no problems reaching it.

Thanks CEH4702 for your answer!!!

I don't think that the low processor power/Bus Speed cause the different speeds in the two ways (Celeron-Athlon, Athlon-Celeron) of file transfer....

It only will be right if the celeron machine was a SQL/ORACLE server that need a lot of memory/cpu power.

I think that the problem may be the network card configuration or a rare motherboard incompatibility...but I'm not really sure of nothing....



Thanks for all!!

Have you looked at the setup parameters of the cards? Usually with a dos based setup utility.
You've answered the card problem with a card change. So you may be trying to transmit at different speeds because the cards recognize the differences in the processors.
You might also want to set the cards to run in simplex rather than duplex. This assuming that they are settable.
