The following is a summary of the responses I received in response to
my post concerning the IDL benchmark "time_test" on Windows and NT
systems:
System: Gateway 90MHz Pentium, 32Mb RAM, Windows for workgroups.
IDL 3.6.1: 15.59 seconds
1st Beta IDL 4.0: 11.23 seconds
2nd Beta IDL 4.0: ~16.8 seconds
System: 486-DX2 66MHz 8Mb RAM IDL 3.6.1: 47.74 seconds.
An error occurred in test #15, resulting in 0.0 seconds for that test.
System: 90MHz Pentium, 32Mb RAM, Windows for Workgroups 3.11
IDL 3.6.1: 16.4 - 16.6 seconds.
Same system except Gateway 90MHz w/ very fast disk: 14.2 seconds
System: 486/33MHz Windows 3.1
IDL 3.1.2: 73.71 seconds.
------------------------------------------------------------ -----
For comparison, my Sparc 10/41 takes 21 seconds.
The Pentium systems are faster, but there are a few points to be cautious
about. Disk speed becomes relatively important with the fast systems. Also,
you will need to run time_test a few times because it gets faster after the
first try.
The big question concerns the two beta versions of IDL 4.0. The first beta is
much faster than 3.6.1, while the second beta is actually slower. Let's hope
RSI keeps the speed of the first beta in the 4.0 release, which is due in late
spring or early summer. Can anyone familiar with these beta versions explain
these speed differences?
Has anyone run the NT version of IDL on a Pentium system?
