The average filesize of maps has rocketed since the release of UT2003.
Some tips for reducing the size of your map:
- set all unseen BSP surfaces to unlit (those completely behind static meshes or terrain)
- set bsp surfaces where shadow detail is not needed to 256
- rebuilding lighting with DXT1 compression
- compress all (custom) textures that don't need an alpha channel to DXT1
