FbNetExternalEngine 5.0 released

18 Jan 2022 1 mins .NET, Firebird

Big step forward for FbNetExternalEngine today. Version 5.0 is ready, you can go and download it right now and it contains some major improvements.

The first big change is update of runtime to .NET 6. Hence you can use all the latest and greatest features and also benefit from numerous performance improvements there. Speaking of performance… That’s the other big change. I’ve spent a lot of time optimizing the code paths, allocations and even number of methods calls or number of parameters. All this resulted in about 9% speed increase (and lower memory consumption), which I’m very happy about. An empty function call is now, on my machine, about 1.1 μs. Also some internal changes opened options for future improvements.

Sadly, one feature had to go. The hot reload via net$clean (or previously net$update). This feature was fragile, difficult to maintain and fit into performance oriented code. Also, I believe the feature was trying to solve problem that should really be solved at another level.

As usual check the docs page as well as the examples directory in the downloaded package.
