[plt-scheme] Appalling performance of DrScheme on Windows

1. I am running a 1.3GHZ Celeron processor with 248MB of RAM (is that the 
info you wanted).
2. DrScheme 301
2a Apart from installing the SimplyScheme teachpack - no (we've discussed 
this before).
3. Just working my way through HTDP - on chapter 11 at the mo.

This sounds indeed like an appalling response time and it makes me wonder 
why some 10,000 people are using DrScheme on Windows. Now I am using 
DrScheme on Windows XP only via Virtual PC on a Mac OS X laptop and it runs 
very nicely there. On my Mac, I am running "large" programs (up to 5,000 
lines, threaded) in DrScheme, leave the environment open for days and weeks 
at a time, and haver very few problems of this kind.

But before we bash Microsoft one more time on this list, let's investigate 
your report in some detail. We don't want to blame them for nothing, right?

1. What kind of machine do you own? CPU speed and memory are two things we'd 
really like to know.

2. Which PLT Scheme implementation are you running? 350? 103p1? Anything in 
between?

2a. Have you modified your PLT Scheme installation in any form or manner?

3. What kind of programs do you run? Are they text-book exercises? Dynamic 
flow equations?

Once we have that information we will figure out how to get you to use this 
thing in an acceptable manner.

Thanks for the report -- Matthias
