I compiled up (from .126) to 2.1.129pre1 (and later pre4) today.
I noticed that for some reason, tar was working very very slowly.
Thought it might be some background or disconnected process eating
up memory/CPU, but top and ps showed nothing. I even init 1'ed and
rebooted...still just as slow.. It would unpack 3 files, then
stop for 7 or 8 seconds, three more...etc.
It did this with every .tar.gz or bz2 I tried. I noted that
both bzip2 and gzip worked perfectly, at full speed. Also
I noticed that:
bzip2 <file.tar.bz2> | cpio -ivud
also worked at full speed. But:
bzip2 <file.tar.bz2> | tar xvf -
was as slow as tar Ixvf.
Is this the scheduling problem that's been mentioned? Or is
this something else. I havent change anything in my setup
recently.
Sysinfo: Pentium 100; 16 Mb RAM ; glibc-2.0.7pre ;
binutils 2.9.1.0.15; linux 2.1.129pre4
Not complaining, just reporting :)
