Data loading time is different across threads #101

Closed JiayunLi closed 7 years ago

JiayunLi commented 7 years ago

Hey,

I am running this code on one GPU with 5 threads. But it seems that some threads have much longer data loading time.

Looks like the first in every five has the longest loading time. I am not sure why this happens.

I really appreciate if anyone could help me with this.
