-Speed
-=====

-CyBlaFB is much faster than tridentfb and vesafb. Compare the performance data
-for mode 1280x1024-[8,16,32]@61 Hz.
-
-Test 1: Cat a file with 2000 lines of 0 characters.
-Test 2: Cat a file with 2000 lines of 80 characters.
-Test 3: Cat a file with 2000 lines of 160 characters.
-
-All values show system time use in seconds, kernel 2.6.12 was used for
-the measurements. 2.6.13 is a bit slower, 2.6.14 hopefully will include a
-patch that speeds up kernel bitblitting a lot ( > 20%).
