Hi Larry,
In fact I made some tests of performance on Penium 90 based machine
(yes I found such a beast ;-)) I was testing 500 stocks database.
And yes, AmiBroker was running still acceptable, but cruicial thing was
memory - that machine had 128MB.
You should be aware that Windows gets at least 3 times slower when
it starts to swap out the memory to the disk.
But.. for 10'000 stocks database it is suggested to have at least 400Mhz machine.
Best regards,
Tomasz Janeczko
