Hi,
Please read the http://www.amibroker.com/newsletter/03-2001.html
for the tips on managing large databases.
Also buy more memory (RAM) for your system. It is really cheap today
and having 256MB will give you much better performance.
Also (if you want to spend some more bucks)
go for AMD Duron processor (800MHz for example). It is cheap and
very powerful. (Note that you will need Socket-A motherboard for this processor)
Best regards,
Tomasz Janeczko
