Exclamation UnTAR ---) Very slow


hi,

I have just extract a bunzip2 file with 722 files for a total of 9.1 mb
And the time for extract was very slow...like a amd 486 DX2 66mhz

extract time: about 14 minutes
Cpu usage: 100%
Average speed: 1mb per 2 minutes

Is'it normal or not?

ohh i forgot this: i use Rehat linux 9 with KDE

CPU: AMD athlon (t-bird) 1300 mhz
RAM: 392mb sdram pc133 crucial
HDD: 7500 rpm Samsung 30 gig scsi

Try this
/////////////////begin ripped text////////////////////
To uncompress a bzip2 file, execute the following command:
bunzip2 filename.txt.bz2 (where filename.txt.bz2 is the name of the file you wish to uncompress)
The result of this operation is a file called filename.txt. By default, bunzip2 will delete the filename.txt.bz2 file.
////////////////end ripped text //////////////////////////////////
from http://www.linuxheadquarters.com/howto/basic/bz2.shtml

oftentimes, it is .tar.bz2 and the following command will leave you with a whatever.tar file. If this is the case try tar -xvf whatever.tar

/me shudders @ the thought of Roothat, but thats just my 3 cents

Well, it depends ... one has to say that
bzip2 is known for good compression,not speed ;)

What kind of files were you uncomprssing?
