Here's how it works. You make an assertion, you get called on it, you
have the choice of backing it up or looking like a twit. You failed to
back up your assertion . . .

O mighty guru, grok the concept--no question is stupid the first time it
is asked.
In any case you made an assertion that if one's web browser slows down
with a large cache, then one should rewrite the cache program. That
leads one to conclude, since you made this assertion without caveat,
that there is some algorithm out there that allows one to write a cache
program that does not slow down with a large cache.
I am asking you to deliver what you claim exists.

So let's see, you have a web page that with no cache loads in 30
seconds. With cache algorithm a it loads in 20 seconds and with cache
algorithm b it loads in 15 seconds. So you're saying that a and b are
equivalent and that all else being equal you would have no preference
between them?

Sounds like it did not get installed. You can get it from the CD, or
ftp.redhat.com (or mirror). It's in its own RPM:
[hal@feenix hal]$ rpm -qf /usr/X11R6/bin/XF86_SVGA

Is there a list of motherboards that are known *not* to have this
problem?
We just discovered that the problems we've been having with our Fibre-
Channel based SAN and Linux is due this this problem. While the above
patch works around the problem for us, it also drops performance too
far for our requirements.
I'm particularly interested in any dual-cpu boards with on-board scsi
that do *not* show this problem!
Thanks in advance!

Thanks for the info Hal.
I did see the RPM on the CD, but without video capabilities I am unable to
invoke _gnorpm_ in the shell in order to install the RPM. I also cannot use
_startx_. Server failure. Very frustrating.

Kppp has modem diagnostics. Open it up and go to the settings and it will test
your modem, send commands, etc. Try that and see if you can talk to your modem
with Kppp
You are using a US Robotics modem so open up minicom and type some modem commands
and see if it responds:
at (hi modem how are you)
ok
at&f1 (resets USR modem to factory defaults)
at&w (saves these settings such as the reset)

I think this is a PNP (Plug and Play Card), so what you do is, go to the
RealTek's website, and go to your cards page and download its configuration
program. In the Configuration program you need to turn of PNP! Then try out
your card. When Linux boots up try 'ifconfig eth0' if you see an "UP"
anywhere in the result you are ready!!!
Goodluck

Do it with the command line:
rpm -Uvv /mnt/cdrom/path/to/RPMS/XF*SVGA*rpm (as root).
Adjust for your path as needed.

I'm running a Duron 700 / Gigabyte board (KT133) without problems. The only
real "gotcha" seems to be the on-board sound (AC97). The kernel drivers for
this don't seem to work! The good news is that the Alsa drivers,
particularly the latest 0.9.0 (I'm running beta3) seem to drive it just
fine. Read the "idiot's guide" at www.linuxnewbie.org
Otherwise, I thoroughly recommend it. Its a lot of bangs for the buck!

Subject: very bad performance. what can I do?
Date: 14 Apr 2001 18:29:20 +0200
Hi ,
few days ago I bought several high performance (at least that's what
I thought) components and build a linux machine.
I use a
- Elitegroup main board (K7VZA)
- a IBM-DTLA-307045 ATA hard disk
- a Aopen 52x CDROM
The machine is connected to my local network with a 100-MBit ethernet
card (with realtech RTL8139).
The board supports UDMA which is also supported by the CDROM and hard
disk.
Performance seems, nevertheless, to be VERY bad (*). Are there some
program to measure the real performance of the hardware? What can
go wrong in a system that slows it down? How can I detect the
bottleneck (or whatever reason there is for the bad performance)?
I'd be very grateful for every hint!!!
cheers,
Jan
================================================================
(*) Without actually measuring the performance (I don't konw how)
I'd say my new system is as slow as my 3 years old pentium 200 machine
with 6 gig quantum fireball and 24x CDROM.
hdparm results in:
# hdparm -Tt /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 1.01 seconds =126.73 MB/sec
Timing buffered disk reads: 64 MB in 33.65 seconds = 1.90 MB/sec

I think this has to depend on the project. General purpose hardware should
have device drivers. However for highly custom things (embedded Linux mouse
trap), it may be easier overall to write directly from user land. When your
code breaks in testing, you don't bring down the machine like you would from
a kernel land device driver.
Its also convient to develop initially in user land, and then later when
software and hardware are sufficiently debugged move to kernel land. This is
expecially true when developing for new untested custom hardware. First
thing you want to know is if the hardware works at all :)

There are no end of logN search algorithms that could be used. They would
slow down, yes, but not significantly over a mere few gigabytes or even
terabytes of data.
For example, you hash the URL to generate a filename and then build a 16-way
directory tree indexed on the hexadecimal expansion of the file to be cached.
Insertion and lookup are both O(logN). Filesystem overhead is negligable for
any reasonable data size.

The popular brand names of thermal printers are Epson and Stars. Most of
them are printing well under MS-DOS, so I think that Linux should be ok
also. But vendors refused to promise anything when they runs on Linux
system.
So, I am seeking advice from experienced user of thermal printer on Linux.
