Tridge and I tried out the postgresql benchmark you used here and this
contention is due to a bug
With Andre's IDE subsystem, I found the below patch necessary to use
my IDE tape drive (Exabyte Eagle TR-4). Frankly, it's been so long
since I created this patch that I can't remember the detailed reasons
for the changes. But I knew them once. :-) And it works for me.
Reminder, this is

Which is exactly what I done on my system. 2MB for command line is
very nice.
Ying-
I'm a little confused here. It's very hard to compare a UP application
vs. the same app. converted to use threads. Unless the app. is
structured such that multiple threads can run at the same time then
no, you won't see any improvement by going to SMP, in fact a true
single threaded app.

You need db3/db3-devel
Which distro is yours ? In my Mandrake 8.0beta there is no /usr/include/db.
Mdk offers the 3 db libs (db1, db2, db3), so I had to create a symlink
/usr/include/db3 - /usr/include/db.
Which is the standard path ? At least, Mdk and RH (Alan...) differ.
Im not too worried about this right now
Hi Ettore,
I have no idea if this is related to your problem since you didn't mention
that key part, but with the same drive, I managed to trash my root partition
incredibly badly by trying to use DMA and then do APM suspend or hibernate.
On wakeup, I'd get an 'hda: lost interrupt' but then
