Hi Zhao Ping,
I created i3en.6xlarge instance, 2 SSDs with 250k iops each (in raid0) and
reproduced your results. Please find dstat output below.
1 worker, io_uring:

62k, BW=2196MiB/s (2303MB/s)(10.0GiB/4663msec)

Hi Zhao Ping,
My test is much simpler than yours. I created
/usr/local/html/(1...9) files on SSD (100 kb size) and wrote small lua

er possible cause is that "/usr/local/html/64746" was changed/removed when
other user tried to read it.
