[Xastir] Speed issues moving maps.

[jd at jdwallace.com]

When I try to pan or zoom I experience long refresh times on the map (10-20 sec). I'm attempting to load 1-5 maps at a time. I'm using scanned maps in .geo format and USGS DRG maps.

I'm using Xastir built from CVS on Ubuntu 10.10 running as a VM on VirtualBox. The host is 8 core/8GB RAM with half of those resources allocated to the VM.

Can someone share some optimization tips to speed map rendering when panning or zooming?

Thanks,
