Here, i did not modify the code like you, and the time cost like this:
classifitime=0.56s current thread===1577723648 0.99840999 - "Test" classifitime=0.57000000s current thread===1586116352 0.99840999 - "Test"
when i modified the code , the time cost stayed the same.
classifitime=0.57s current thread4275218176 0.99840999 - "Test" classifitime=0.61000000s current thread4266825472 0.99840999 - "Test"

I didn't use the gpu_allocator.cpp files, I only use your context and pool files, is the gpu_allocator files important, thanks!!
