Thread: sac-101.4 on Ubuntu is slow?

I just downloaded the newest

sac-101.4-linux_x86_64.tar.gz

for my Ubuntu workstation:

uname -a

Linux slab 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010
x86_64 GNU/Linux

I tried to read 700 *.sac files each of which is 70Kbyte,

r *.sac

but it took minutes to read/load them into the memory. After I loaded them
into memory, I tried

SAC> sort gcarc

and it again took minutes ...

Is there something wrong with my machine? Previously, I was using sac-101.2
on RedHat and it was very fast especially the sorting feature.

Any idea? Thank you.
