If I use Servicestack with ASP.net Core, will the performance be close to raw ASP.Net Core as per the https://www.techempower.com/ benchmarks where ASP.net Core is high up. However, when you look at where Servicestack sit, it is very low down on the performance list. I have been using Servicestack for years and need to know if I should go to native ASP.Net Core or continue using Servicestack on ASP.net Core
The ServiceStack submission someone else contributed many years ran on old ASP .NET Framework + Mono (behind a reverse proxy) which has extremely poor performance as visible by all other aspnet-mono* entries.
If you’re running ServiceStack on Linux you should definitely be on .NET Core where you’ll benefit from all the perf work that’s Microsoft has put into Kestrel + http libs over the years. ServiceStack itself effectively runs as lightweight handlers over the underlying HTTP Server comparable to Web API or MVC and optimizes where possible, e.g. uses forward-only buffer, async writes/reads, aggressive delegate caching, etc.
Although don’t expect the raw perf numbers listed on techempower, they’re not real-world examples, they’re more to test max theoretical throughput.
