On my Intel e8400 running @ 3Ghz sorting 10 columns * 2000 items takes ten seconds. Is there anything that can be done to considerably improve performance here?

This is in Release mode. It’s faster for me to read the database into memory, sort the memory & re-build the grid ... this can’t be right???

This is not exactly similar to Release. The debugging information is on.

The grid controls in Debug version are much slower then in Release due to heavy assertions everywhere. Please take a look at the beginning of the .../Prof-UIS/Include/ExtGridWnd.h file and check the following:
1) The following lines should be commented:
// #if (defined _DEBUG)
// #define __EXT_DEBUG_HEAVY_CHECK_GENERIC_REGION_2D
// #endif // (defined _DEBUG)
2) The following lines should be uncommented: #define __EXT_DEBUG_GRID_ASSERT_VALID( __PTR__ ) ;
#define __EXT_DEBUG_GRID_ASSERT_KINDOF( __CTYPE__, __PTR__ ) ;
#define __EXT_DEBUG_GRID_ASSERT( __SOME_EXPR__ ) ;
#define __EXT_DEBUG_GRID_VERIFY( __SOME_EXPR__ ) __SOME_EXPR__ ;
3) The following lines should be commented: // #define __EXT_DEBUG_GRID_ASSERT_VALID( __PTR__ ) ASSERT_VALID( __PTR__ ) ;
// #define __EXT_DEBUG_GRID_ASSERT_KINDOF( __CTYPE__, __PTR__ ) ASSERT_KINDOF( __CTYPE__, __PTR__ ) ;
// #define __EXT_DEBUG_GRID_ASSERT( __SOME_EXPR__ ) ASSERT( __SOME_EXPR__ ) ;
// #define __EXT_DEBUG_GRID_VERIFY( __SOME_EXPR__ ) VERIFY( __SOME_EXPR__ ) ;
