Well.... I loaded a RAMDisk program called Dataram RAM Disk and moved the entire database (333mb) over there. Started AmiBroker and of course it asks where is the data and I point it to the new database. I run the same Explore and guess what....NO faster....It still took 2 minutes and a few seconds to process the Explore.
So what do make of that ?
