NIOS II C/C++ IDE; launching app very slowly

Hi,

If I build my application the first time it takes ~5 min. That's normal.

If I build it again, it's faster, ~1 min. That's nomal, too.

but: If I launch the application (in this case simpleSocketServer) it takes 5 until 7 minutes. That's much too long. What could be the reason for this problem...?

nios ii integrated development environment

version: 8.0

build: 214

Regards,

Stefan
