Varying speed of a program.

[matalog]

Running this program 4 times, I get 4 different runtimes, increasing from time of startup. 187,288, 190,297 and 199,373 200,310.

Code:

EXPORT SPTEST()
BEGIN
DIMGROB_P(G1,320,240);
DIMGROB_P(G2,320,240);
LOCAL T1:=TICKS;LOCAL T2:=0;LOCAL T:=-1;
RECT();
    FOR X FROM 0 TO 5000000 DO
     IF X MOD 50000=0 THEN
       T:=T+1;
       RECT_P(G2,0,0,320,240);
       TEXTOUT_P(STRING(T)+"%",G2,0,0,7);
       FOR H FROM 0 TO 30 DO
          FOR W FROM 0 TO 50 DO
             FOR A FROM 0 TO 3 DO
               FOR B FROM 0 TO 3 DO
                   PIXON_P(G1,80+W*4+B,50+H*4+A,GETPIX_P(G2,W,H));
               END;
             END;
          END;
       END;
           RECT_P(G0);
           BLIT_P(G0,0,0,320,240,G1,0,0,320,240);
     END;
    END;
T2:=TICKS;
PRINT(T2-T1);
END;

Are you saying that this is a known problem, and someone is looking into it?
