Well, you need to remember that ka-map draws a meta tile which is
typically 5x5 regular tiles so it need 25 times the image memory
required to draw a single tile. This may cause your system to page to
disk which would REALLY slow things down.
You can try making your meta tiles smaller, or add more memory. Other
than the larger memory requirements and the effort to chop and store the
individual tile, it is just mapserver running.
You cant to make sure you do NOT have the force option configured ot it
will regenerate the tiles on EVERY request which is not what you want.
Are things fast, if you pan across an area that you have already panned
over in the past, ie are you pulling cached tiles or are you generating
the tile again?
