[ka-Map-users] Performance problems

We've a site running KaMap that has run with acceptable performance for
a number of years. The shapefiles were recently upgraded, and now the
Looking in the Apache logs, I'm seeing:
msDrawMap(): Layer 9 (ADDRESS), 125.109s
msDrawLabelCacheGD(): labelcache_map_edge_buffer = -40
msDrawMap(): Drawing Label Cache, 129.358s
If I'm counting correctly, Layer 9 is an annotation layer containing
street addresses that is drawn only at very tight zooms.
When I run shp2img, with the extents closed down so that the address
layer is drawn, I see:
msDrawMap(): Layer 9 *ADDRESS), 0.532
msDrawMap(): Drawing Label Cache, 0.547s
Any idea as to why drawing this layer would be so much slower, when done
by KaMap from Apache, than when done by shp2img from the command line?
