I tested GTK+ over DirectFBs performance using gtkperf tool.

Test result surprised me.

Below is my test result using $./gtkperf a c 100 in my target.

 

GTK+2.6 over Tiny X : 97.14 sec

GTK+2.8 over Tiny X : 160.28 sec

GTK+2.9 over DirectFB : 458.65 sec

 

I know GTK+2.8 is slower than GTK+2.6.

But I cannot understand why GTK+ over DirectFB is much slower than GtK+ over TinyX.

Many reports said that DirectFB is slower than TinyX,

but they didnt explain the reason of bad performance.

 

If anyone know the reason, give me some information please.

 

Best regards
