AW: [Seaside] Re: Concurrent requests from multiple sessions

I don't know VAST, yet in VisualWorks you can call "Processor yield" in your process which will give way to other processes. By that you'll get a simple "parallel" execution of your processes.

Just to be sure that we are wasting enough time, you might want to make that

    100 timesRepeat: [1000!]

But assuming that makes no difference:

So that's the issue. Squeak and Pharo rotate the order of processes at a given priority whenever one is interrupted by a higher priority process. VAST appears not to do that (or there are no higher priority process running...). IOW,

Squeak and Pharo offer a Poor Man's Time Slicing, although with no guarantee that the slices are equal in width.
VAST offers what seems to ensure a process will not be pre-empted by another process at the same priority (which has a certain logical appeal ;-) ).

Not having access to VAST, I can't tell you if this difference is accidental or intentional. Perhaps someone know a bit more...

What happens in VAST?

I tried it in Workspace (but 10000! caused a stack overflow, so I used

1000!). The result follows:
