*very* sluggish at 100Mb/s but OK at 10Mb/s??

An Intel RC440FX Pentium Pro server with onboard EtherExpressPro100B at eth1 (and also a ISA Pro10+ at eth0). RedHat 6.0, kernel 2.2.5-22, hub is an Intel 330 (330T? I think) which is auto 10/100. It is running a mainly NT network at mostly 100Mb/s, though a couple of 10Mb/s nics, and I have a feeling that the NT machines are not running full duplex - not sure whether this is controlled by the hub or by the settings on the individual machines?
(BTW this server has onboard scsi, and I see in the archives of the list that this has been an issue in some cases).
I have added this linux server, and the performance of the 100B is atrocious!! I ftp'd a file from it at about 6kb/s! and uploading was much worse. In fact I haven't had a successful upload - trying today to upload a newer eepro100.o the upload never got beyond 2k completed before timing out.
I've installed the 1.09l module after downloading from the web page, but no better. It runs fine if I force 10Mb/s or 10Mb/s full duplex, but hopeless on 100Mb/s whether half or full. There follow the diagnostics, the first set are after installing the module with no options, and the second set are after forcing it to 10Mb/s with options=0x50
Any suggestions folks? Thanks.
