Optimization improves writing larger all-ASCII strings.

  • 105 and 10080 bytes are much faster
  • 10 is on the border, but shows a small improvement
  • 1 and 4 use existing path

The other writeString optimization PR has been merged, let's rebase?

The C# build is currently failing:

A compatible installed .NET Core SDK for global.json version [5.0.100] from [/tmp/protobuf/protobuf/global.json] was not found
Install the [5.0.100] .NET Core SDK or update [/tmp/protobuf/protobuf/global.json] with an installed .NET Core SDK:

A new enough version of the runtime needs to be installed in the test scripts or in the dockerfile.

Benchmarks that use the new path are 105 and 10080 length strings. Both are much faster:

I've attempted to fix this but can't trigger the build to test. If it doesn't work can you finish making the changes required here.

Are you sure that is on Windows? The paths in the error message look like its Linux.

I think this is the problem: NuGet/Announcements#49

I think this fixes the Linux restore issue:

- FROM debian:stretch
+ FROM debian:bullseye

Looks like I've been able to update the CI stuff so that the tests are now passing.
Left a few more additional comments (we're almost there).
