Looking at the signal with a scope is probably a good idea. Here is an
update from today's fun.
1. These is an error in the fcc_enet.c file which causes NO and CRC errors
when running in full-duplex mode. fcc_restart() should be updated to include
FCC_PSMR_LPB when configuring full-duplex mode. (cleared when not)
2. Some relative performance measurements (HHL 2.4.2 vs. 2.4.19pre9)
10T Hub | 100BT switch
-------------------------------------|
2.4.2 | 410KBps | 750KBps |
-------------------------------------|
2.4.19 | 440KBps | 190KBps |
--------------------------------------
RedHat 2.4.18-3 (x86) 3900KBps
3. TOP shows as much as 48% system utilization during a single FTP transfer.
With the fix mentioned in #1, there are 0 errors reported by ifconfig.
I may be missing something but I believe that these numbers are going the
wrong way. There is still the question of performance decrease when using a
100BT switch. Signal intregety can not be the only suspect considering the
performance did increase using an older version of the kernel. (although
nothing like the Workstation performance)
