Hello,
Backfill is entirely handled by TWS / API. You should keep in mind
that while AmiBroker is native Win32 application (small and fast),
TWS is Java-based program. All Java-based programs are way bulkier
than native apps and take more resources than native applications.
See TWS system requirements:
http://www.interactivebrokers.com/en/software/requirements.php?ib_entity=uk
800 Mhz (Athlon), 1GHz (Celeron) is minimum system for TWS !
AmiBroker itself runs fine on 166MHz cpu.
So it is not a problem of AmiBroker but TWS.
Best regards,
Tomasz Janeczko
