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 > use linux native aio > -------------------- > > Key: TS-1760 > URL: https://issues.apache.org/jira/browse/TS-1760 > Project: Traffic Server > Issue Type: Improvement > Components: Core > Reporter: weijin > Attachments: native_aio.patch > > > add a feature that use linux native aio -- This message is automatically generated by JIRA.
