Esparta,

XMLToCursor is most definately not linear in performance. Try this test code:

function BigXMLTest( n )

close databases all

create cursor x1 ( i1 i, c1 c(10), t1 t, i2 i )

for i = 1 to n
   insert into x1 values ( i, str(i), datetime(), int( rand() * 100000 ) )
endfor

? n
i = seconds()
cursortoxml( "x1", "x1.xml", 1, 0 + 512, 0, "1" )
?? seconds() - i

close data all

i = seconds()

xmltocursor( "x1.xml", "x2", 512 )
?? seconds() - i

CursorToXML() is linear in performance.
