Hi Team, As expected, I can see there are good numbers in the performance by using UDS (Unix Domain Socket), please checkout the results (extracted using Iozone benchmark tool attached above) Steps to see the results in html file: $ unzip gluster_iozone_results.zip $ cd gluster_iozone_results/ $ firefox html_out/index.html Helpful Background: https://www.iozone.org http://iozone.org/docs/IOzone_msword_98.pdf https://en.wikipedia.org/wiki/Box_plot Cheers, - Prasanna [ sorry for trimming all reply's ] On Friday, November 6, 2015 12:38:25 PM, Prasanna Kumar Kalever Wrote: > > Hi all, > > Currently we use TCP loopback connection for communicating between gluster > Client and Server. > Hyper-convergence may also require communication with a server running in the > same hyper-visor. > > I was initially wondering if replacing IPC with Unix Domain sockets will > improve the performance? > Or > Is there any theory that proves that Unix Domain socket would give better > performance then TCP loopback connection? > > Finally I have to Say: > > Yes, local IPC by unix domain sockets will be faster than communication by > loopback connections because you have less TCP overhead > > Postgres core developer Bruce Momjian has blogged @ > http://momjian.us/main/blogs/pgblog/2012.html#June_6_2012 about this topic. > Momjian states, "Unix-domain socket communication is measurably faster."
