tar.bz2


Just curious why files.tar.bz2 are so slow to unpak?

Im running RH 8 > kde and just double clicking into the tar and copying out the dir... is this a bad way to uncompress bz2's?

I have tried with the Archive tool and it isnt any faster (I'm talking like 25 mins for a 4 mb file) is this normal?

i don't know why it would take that long, but just try it at the command line and see if the same things happens:
tar -jxvf file.tar.bz2

it can be normal on a slow system (386) but it really should go fast, also if you ide controller is not identified properly it can do it, do an lspci and a dmesg and post oth outputs here and I can check for you

try:
Code:
time [file.tar.bz2]
to get an exact time. Then post it here. Also, if you have a couple of machines, try it on each of them to compare.

some things like kde run ast becuase they are loaded into memory, .bz2 files are not. just give me the output of hdparm -i /dev/hdX

well, it is using dma and ata/100 so the hd/controller is not likely the option. what distro/version are you running, and do you have a custom kernel?

ick.
1) I personally hate redhat
2) redhat 8 was a feature release and probably had a lot of bugs (redhat had .0 as feature, .1 .2 and .3 as fix released until 9.0 mwhe they changed the scheme, try recompiling tar (with the bz2 patch) or d-load a newer rpm
3) stock kernels aren't always the best, you might look into compiling your own kernel (not as daunting as it may seem to be)

you might look into slackware (my favorite) or debian (I didn't like it but those that do are excessivly religious about it (like a mac user on crack religious))

I am also on dialup, for $20 you can buy slack on www.slackware.com, or you can use a d-load manager (gtm) to d-load iso's over a few days.
