Hello, 25% speedup is in processing large arrays with lots of floating point calculations. It also depends on CPU used. On some CPUs 64-bit version may use SSE/SSE2/SSE3 extensions giving better results. There are way too many combinations of CPUs/formulas that you use/amount of data/etc to get a single "speedup" number. Therefore I use "a bit faster" because it is always true.
CMAE is included in 64-bit version. Best regards, Tomasz Janeczko amibroker.com On 2010-07-08 09:43, Rob wrote: > Interesting. TJ used to claim that the 64 bit version was 25% faster.
