I haven't personally run PicoGUI on anything slower than an Agenda VR3 in a long time. You could run gprof to find the bottleneck, but it's almost certainly the video driver. What video driver are you using, and at what color depth? pgserver also has a benchmarking mode for quantitatively measuring video speed.
we use the depth is 1bpp, and the benchmarking is flowing,
load video driver successfully, name is vz328
vidw, vidh, vidd, vidf = 160, 160, 1, 0
Running video driver benchmarks...

To have an idea about what will be the behavior of the programs on our
platform, we used the XCopilot emulator on pc. Is this also what you
spoke
about when you said "... when run in PC, it's ..."?
when we debug on X86 platform, we use SDL as video driver on XWindow
Unfortunately, I don't have one that works here... but if my memories are
right, it wasn't possible to have such informations with the 2.0.x
kernel.
Thanks. we had used 2.0.38.kernel when we use M68EZ328 , we also can find in /proc/cpuinfo file.and the speed about 1.4BogoMips sanit(or maybe it was something else that wasn't accessible...) Anyway, if I could get some info, I'll tell you.
