Maybe you are right. The SCSI drive is a external (5 or 10 MB per sec ?) in
an older G3 (but not an upgraded) with an SCSI port still directly on the
board. There is no network connection at all. Hope you know which one I
mean, this beige G3 with 233MHz. There is no network connection at all. On
the weekend I will format the external drive and/or reinstal my system.
On the blue/white G3 here in my Office, IDL is running very fast. Here the
G3 has the same Operating system, (less memory), the same IDL version with
the same Demo license.
So, another thing we observed is, that a big calculation a P3 with 900Mhz
and 512MB took 42 secs, while on a Mac the same calculating only took 22
secs. Does somebody have experience in performance comparison Mac<->PC ???
Systems:
blue/white G3 with 400Mhz, 256 MB, MacOS 9.1, internal IBM SCSI drive with
an Adaptec SCSI Controller
Siemens PC with P3 900Mhz, 512 MB, Windows 2000, normal internal Harddrive
(IDE)
