I am not familiar with the low-level stuff so bear with me!
[Q.] What is the performance of Linux if it is forced to
use a non-native file system? i.e. suppose that
we are forced to access (masses and masses of) data
that are stored on NTFS but we have the choice of running
Linux, then what is the performance likely to be vs ext2?
How does the file system affect the performance of any
OS for that matter?

Last time I tried, Linux NTFS driver is not stable enough for writing.
DOS file system is quite stable, but you have to be root all the time.
NFS file system is difficult to deal with if files are owned by root.
I do not notice much differences in performance. Those are just my
limited experiences with file systems.

I'm using an HP C1553A autoloader for doing tape backups. It holds 5
4mm tapes and allows for quick backups of DDS-2 tapes for up to 4 GBs of
data. Just wondering if anyone has used this same piece fo hardware
with dump and has been able to get it to automatically switch tapes when
one is done.
I personally like dump and have been pleased to se its progress in the
last while. It's getting closer to the Solaris ufsdump utility.
Thanks.

There is on some Intel chipsets, which refuse to cache more than the
first 64M of RAM. Things that load in the 'uncachable' memory would be
slower. To my knowledge, this only affects chipsets for the plain old
Pentium (ie, socket 7) line, so if you're using a Pentium Pro, it
shouldn't be a problem.

Subject: switching to FVWM from KDE
Date: 11 May 2000 20:19:26 GMT
HI, I've installed RH6.2 as a KDE workstation. I've noticed that
my netscape keep hanging, apparently because of a bug in the JavaVM
(applets cause it to hang).
IN ANY CASE:
I'd like to try running FVWM instead, is there any way I can easily
switch over to using FVWM without major reconfiguration? Perhaps
I can set it up so I can start up either of the two?
Any ideas?
Thx!

Do this incantation:
cp /etc/X11/xinit/Xclients ~/.Xclients
Next, edit your Xclients to have this line added here:
# check to see if the user has a preferred desktop if [ -f
/etc/sysconfig/desktop ]; then
if [ -n "`grep -i GNOME /etc/sysconfig/desktop`" ]; then
PREFERRED=gnome-session
elif [ -n "`grep -i KDE /etc/sysconfig/desktop`" ]; then
PREFERRED=startkde
elif [ -n "`grep -i AnotherLevel /etc/sysconfig/desktop`" ]; then
PREFERRED=AnotherLevel
fi
fi
PREFERRED=AnotherLevel # Add this line here
[Rest of your .Xclients file]
Next, you need to perform a text-based login, and start up X with
'startx'. Edit /etc/inittab so it has a line that looks like this in it:
id:3:initdefault:
Instead of:
id:5:initdefault:

Subject: netscape hangs in RH6.2 KDE
Date: 11 May 2000 20:26:47 GMT
HI, I've installed RH6.2 as a KDE workstation. I've noticed that
my netscape keep hanging. If I open multiple browsers, if one
hangs it often causes the others to hang.
I've noticed that running the JavaWebServer admin applet (a large
applet) causes it to hang very quickly every time, it seems to
only happen if there is one other netscape open at the same
time.
On my old machine I ran the same applet with 8-10 browsers open at
the same time never with any problem. That was with RH6.1 using
FVWM(2?).
Has anyone experienced this problem?

I think you missed the point. Some of us want accessibility to their home

Remember, however, that the ghettos that the SS set up in Warsaw and
Theresienstadt (to mention two), have little to do with the medieval
ghettos that existed in nearly every larger town up to the 19th
century and sometimes even later. E.g. the Prague ghetto ceased to be
a ghetto some year in the middle or late 1800s.
The SS "ghettos" were a sick, perverted and megalomanic caricature of
medieval ghettos, conceived to be murderous by the simple
circumstances of the lives of the people within.

Hi-
I'm trying to setup a Laserjet III without PS cartridge, to print from a
Slackware 7.0 system. I've tried apsfilter, but it didn't work. I'm
currently trying to make it work with ifhp (3.3.10), but I cannot get
the ifhp.conf right, and the documentation is extremely confusing. Even
the tests they suggest after installing the package don't give me the
expected output. BTW, I'm using BSD LPR, not LPRng, but as long as the
printcap is OK, it shouldn't matter, right? I'm able to print from this
machine to another laserjet printer, a HP4000N, over the network,
without trouble.
So, if someone has a working ifhp.conf for a LaserjetIII, please e-mail
it to: stamasd(at)excite(dot)com.
Thank you!

You can't, since WFAT has no concept of security settings for files. NTFS
has this concept, but since most Windoze applications don't have a concept
of security settings for files, most directories on a NTFS file system
have to be wide open.
Anyway, Linux's NTFS support is spotty.

Not for properly written programs. This really only hozes poorly written
shell and Perl scripts.

YMMV on that... I found it worked fine, but I didn't play with it for more
than an hour.
>DOS file system is quite stable, but you have to be root all the time.
Nope. Adding the right incantations to /etc/fstab will allow ordinary
users to access a FAT partition, or allow all users at once to access it.
Main problem is that every file on said FAT filesystem will be owned by
the user who originally mounted it, since FAT knows nothing about
security.
>I do not notice much differences in performance. Those are just my
>limited experiences with file systems.
can't say too much for NTFS, but performance suffers a bit on FAT. Like
so:
time dd if=/dev/urandom of=/win/crud bs=1024 count=4096
real 0m25.689s
user 0m0.010s
sys 0m23.480s
time dd if=/dev/urandom of=~/crud bs=1024 count=4096
real 0m24.581s
user 0m0.010s
sys 0m23.170s
It's worse if there are a lot of file seeks--fragmentation on the FAT
partition and all. Another test with mkisofs showed that having source
and destination files on FAT32 took about 310 seconds, while having those
files on ext2 took about 207 seconds. HTH,

I hadn't thought of sending it to a mobile but heh ! good idea. I reckon
that if I could set up a microphone attached to sound card and monitor for
sound level ,if it triggers it could sound an alarm , or record a picture
and email me the picture or at least keep for records to give to the
police. I can write a java program to pick up the picture and email it - it
is the monitoring of the sound level that is the problem - I maybe able to
write this in Java ( as I don't know C that well)
Any help from anyone would be most apreciated though.

The two things that cause netscape 4.x to hang:
* Slow DNS lookups
* Java Script
Solution:
* Use a cacheing nameserver, to minimize the DNS lookup delay
* disable java Script, which you should disable anyway for security
reasons
