bicubic maps are much slower!

GM14: I loaded some png files into a map catalog and activate bicubic. I save all in a workspace. Opening this workspace takes up to 30 seconds. The same workspace saved without bicubic mode opens in 5 seconds.
The same wirh export to ecw. It takes up to five times longer.
In GM 12 these problems do not occur.
