Having just upgraded from a 10Mbps hub to 100Mbps, I was surprised that transfers to the NASLite+ were still resolutely sat at almost exactly 10Mbps. Other network transfers (e.g. same files from same desktop to laptop) ran at about 70Mbps.
NASLite+ is a Cyrix P150+ with 48Mb Dram . NASLite+ is V1.1. Hetwork card is Realtek 8139D with System info showing the link up is 100Mbps. Only Disk is an 80Gb Hitachi.
Am I expecting too much from my hardware or is it necessary to update the boot CDROM?

Is that 10Mbit per sec or 10MByte per sec?

I suspect that your Cyrix motherboard only has ATA33 IDE controllers so that is the limiting factor.

Even if you upgrade to gigabit LAN you want see any difference.

This is the same issue I have, on a 10Mbit LAN, I get consistently 7Mbyte per sec transfers from and to the NASLite+ box.

The 10mbps (10Mbits/sec) hub has been upgraded to 100mbps (100Mbits/sec or 12.5Mbytes/sec)

The motherboard (Gigabyte 586HX) is limited to PIO Mode 4 for data transfer to the disk but I thought this was about 16Mbytes/sec. At present my file transfer to the NASLite+ is about 10 Mbits/sec (1.25Mbytes/Sec).

Is there something I am missing?

1.25Mbytes/sec is slow.
Is it a new 100BaseT switch or a hub?

Note however, that 12.5Mbytes/sec is a theoretical maximum since that is the speed at the physical layer. If you add protocol etc overheads, and network contention the figure comes down a bit.

You mention that in your motherboard's BIOS you set IDE to PIO4.

Have you tried disabling the BIOS settings for IDE (as per manual)alltogether and let NASLite+ do its thing?

In your initial post you mentioned something about moving to CDROM boot?

NASLite+ is the CDROM version.

What do you boot from now?

I agree that the lack of speed increase is most likely due to inherent spped limitations on the mainboard of your machine.

See this post for a fuller explanation of how the mainboard and its BIOS affect NASLite performance.

Thanks for the inputs guys - looks like I will have to live with it.

ALucas - for your info:

The new 100BaseT is a switch & gives up to 10MB/s transfer between other computers.

Just checked the NASLite+ & I obviously forgot to set the BIOS to "None" for the IDE drives -RTFM error!!

If I do it now, the system will not boot as there is a "none system disk". I assume I would need to go through the initial config setup again to correct this but would this lose the data already on the NASLite+ drive?

I am booting from CDROM so my initial comment regarding this should be ignored.

In BIOS setup only set to None the IDE Disks.

The channel which has your cdrom on it should be enabled to CD-ROM.
