Is the network performance of .Net Core differs much between Windows Server and Linux?

Question

User-2104422214 posted

Hello,

I'am trying to find some benchmarks comparing Windows Server with Linux regarding network performance(maximum number of req/sec, Mpps figures, etc).

https://www.techempower.com/benchmarks/#section=data-r19&hw=ph&test=plaintext

The above link features only Linux as a host - are results on Windows Server comparable? Where could I find them? Does the current Windows Server network stack is a good as Linux? Could it scale to millions req/sec like Linux from the above link?

Thank you

Here is a comparison on azure

But this is only part of the story. Your performance will depend on what other features your code is using. Also these tests are for trivial sites. But current versions of asp.net core are well tuned for linux, because it’s the most common server for benchmarks.

Thanks for the link.

Here is another one: https://www.ageofascent.com/2016/02/18/asp-net-core-exeeds-1-15-million-requests-12-6-gbps/

I'am probably already some sort of vestige but I'am enjoying programming and deploying on Windows more than on Linux(more convenient for my exp). The problem is nowadays all focus is so shifted towards Linux that I'am starting to feel I'am in a sort of ghost town with my OS preferences. :)

If there are more links/data/personal exp. comparing Linux vs Windows network performance please share, thank you.

Also, anyone knows - does ASP NET [Core] on Windows is taking full advantage of RIO?

ASP.NET Core won't do anything that is OS specific.

You mean it uses something like select() to query for sockets state? :D

Windows should remain a first class support for asp.net development or hosting  for the foreseeable future. Microsoft’s current push is to host in azure rather than locally.  A second focus is container and server less support. This removes the O/S from the equation.

To improve network and streaming support, .net core created their own low level buffering support rather than use RIO (which is O/S dependent).  See
