yt.load() doesn't do any I/O beyond reading some simulation metadata so
there's likely still I/O contention happening in your script.

Hi Britton,
Thanks for your prompt reply. I followed your advice that move I/O step outside the duration of timer[1] and make the total time longer, and then I obtain the scaling [2]. Look at figure[2], we can see that the performance of 2 cores is only 124/112~1.1 times better than that of 1 core. Does this make sense? Hope I really miss something because I have a huge data to be analysed. Thanks.
