WTK emulator extremelly slow doing gfx

I have a simple J2ME game app running in 176x208 screen. The app does only two 176x208-sized Images blitting (in overlay). This occur 17 times per second.

Using WTK emulator my app loads PIII-650/1Gb ram/Nvidia Gforce4 machine about 100%

Why?

My app works fine. All other emulators (Nokia, Ericsson, Siemens) work very well, the load is no more %5-10%.

What can I do?
