Zhao Yongming commented on TS-1760:
-----------------------------------
1, it is a configure option:
+# If the OS is linux, we can use '--use_linux_native_aio' option to
+# replace the aio thread mode. Effective only on the linux system.
+#
2, I think that is because that glibc aio is a user thread implement like our
own AIO, and we need some performance improvement in this patch, in our
testing, the cpu usage may get 5% less than origin threading AIO, and the disk
hit response time may get into 5-10ms, that is much better than before.
Weijin should post some more data here :D
