[amibroker] Re: No performance increase with RAM Disk and CDI data???

Have you used the AFL Code Profiler (AFL Editor: Tools->Code Check & Profile)?  You can determine which functions are consuming the most time and sometimes find faster ways of implementing them.  For example, I found WMA (weighted moving average) to be much slower than EMA (exponential moving average).  Changing from WMA to EMA made my system several times faster (this was a while ago so I don't remember the exact performance improvement numbers...).

A few years ago I thought my code was too slow so I ported most of it to a DLL.  Much to my surprise, the performance of native AFL was about the same as using the compiled DLL plugin.

Regards,

David

I copy the database to the Ram disk and reset Amibroker(5.2) to use it, but get no increase in performance. My one year database is about 150mb.   An `Exploration' takes about 30 minutes either way. I'm beginning to think that my code size (2k+) might be the problem.
