Network Performance Testing Summary

2001-06-05 Thread John William
This is a follow up message to the original "Abysmal Receive Performance" message. Thanks to everyone who e-mailed me with suggestions. Well, after poking around, I eventually narrowed the problem down to the fact that the system BIOS did not enable PCI->RAM write posting. After I enabled that

Abysmal RECV network performance

2001-05-27 Thread John William
Can someone please help me troubleshoot this problem - I am getting abysmal (see numbers below) network performance on my system, but the poor performance seems limited to receiving data. Transmission is OK. The computer in question is a dual Pentium 90 machine. The machine has RedHat 7.0 (ker

[PATCH] HP Vectra XU 5/90 interrupt problems

2001-03-13 Thread John William
I propose a patch of mpparse.c (patched against 2.4.2) to fix the Vectra XU interrupt problem. By the time we get to construct_default_ioirq_mptable(), we know we have an ISA/PCI machine without any IRQ entries in the MP table. At this point the kernel would just set up all the IRQ entries as

HP Vectra XU 5/90 interrupt problems

2001-03-10 Thread John William
I'm having a problem with kernel 2.4.2-SMP on my HP Vectra XU 5/90. This is an old dual-pentium (Neptune chipset) machine. The machine has an on-board SCSI and ethernet controller, and I have added a Netgear FA310TX card. Due to the "unique" design of the motherboard, all the PCI slots share a
