Joe,
The additional checks induce delay only during Database Settings->Configure->Retrieve.
There is absolutely no additional delay during regular explorations / backtesting.
Actually with new plugin they may run slightly faster because the database does
not contain any empty symbols.
*New* (todays) QP2 plugin 1.5.1 is available already
http://www.amibroker.com/bin/QP2.dll
Best regards,
Tomasz Janeczko
