New build optimization much slower since 1200.4785

Postby glam_100 » 27 Jul 2008

Hi,

I've brought this issue up before referring to this post http://forum.tssupport.com/viewtopic.php?t=5231

The latest build MC 4.0 Beta (build 1440) is even slower than 3.1 Beta.

This is the test result I got for the 3 different builds:

Test symbol: SPY
Date: 12/31/2001 - 12/31/2003
Interval: Daily
Signal: Bollinger band LE (1..50, 1..5) and Bollinger band SE (1..50, 1..5)

result:

MC 3.0 release - 40sec
MC 3.1 beta - 1:40 sec
MC 4.0 beta - 2:40 sec

Please MC team please find out the reason. I know there have not been other reports of the issue but it does not mean the problem is not there. Maybe most people wouldn't bother to switch back and forth builds (needs reinstallation!) to test it. I've attached screen shots.
Screen shot 1-7 is taken from MC 3.0 release showing the symbol settings and optimization parameters as well as the time it took. It took 40 secs.

Screen shot a and b is taken from MC 4.0 Beta using the exact same settings. It shows it took 2:40 sec

By comparison it takes TS 3:40 secs to finish this job using 1 core. MC is going backwards from being vastly superior in performance (40 secs) to only slightly better in performance (2.40 secs) comparing to TS since the last 3 builds and MC is using 4 cores!!!

Please help~~~
