The problem with QueryPerformanceCounter is that some folks raised concern on the stability of the measurements when comparing two distant points in time, although I haven't tested validated that concern yet.

In `src/testing
/testing_windows.go` you have an example of how to use it.

amd64 and arm64 should have similar timer/timestamps resolutions. Go timers already use high resolution timers on both platforms, and you can get a high resolution timestamp (<1us) by calling QueryPerformanceCounter. This last one is still not used by time.Since, but it is used in test benchmarks.

πŸ”₯Keynote Speaker Announcement

We are delighted to announce that Roland Shoemaker will be a key note speaker at this year's #gopherconuk.

Roland leads the Go Security team at Google, working on cryptography, transport security, vulnerability triage, and generally keeping Go secure. Before working on the Go team, he worked on the Let's Encrypt project building the certificate authority software which now issues millions of certificates each day.

Despite its 15 year history, Go has had a rather uneventful security history. In his keynote, Roland will talk about why that is, some of the mistakes made, and what they learnt. Along with what he's working on now, and what’s on the horizon to make Go an even better, safer language for the next 15 years.

Buy your tickets over on our website & join Roland as he opens Day 1 of our conference on 13th August 2025.

🎟️ https://buff.ly/Azghzwp

I don't think they post here, but excited to be talking about what the Go Security team does, and why (hopefully) you don't hear much about us, at GopherCon UK in August.

Porting the TypeScript Compiler to Go for a 10x Speedup
The Overview, Room TBD, Level 5, North Javits
From the beginning, the TypeScript compiler has been self-hosted, evolving alongside a growing ecosystem of millions of developers. As time went on, we faced challenges with the compiler's performance, largely inherent to the implementation language itself. Through experimentation and testing, we found Go to be an excellent language for our specific needs; a perfect porting language. In this talk, we will explore the process of porting the 150,000+ line TypeScript compiler and its 90,000+ tests to Go, the challenges we faced, lessons we learned, all leading to an overall 10x performance improvement over our previous implementation.

Talk/Attendee Level: Intermediate

Picture of me, with:

Jake Bailey
Senior Software Engineer
Microsoft

Happy to say that I'll be speaking at @gophercon.com 2025 about TypeScript's port to Go!

There's a lot of interesting stuff to talk about, from the effort's inception, the actual process of porting, and all of the Go stuff we learned along the way (gotchas, perf).

Found this tonight and it's a really solid read on the Go runtime. Definitely a long post but it's got a lot of useful info in it.

Learned a lot about things that I haven't really dug into before from it.

JEP 449 says this:
> Windows 10, the last Windows operating system to support 32-bit operation, will reach End of Life in October 2025.

Is there an official statement from Microsoft saying that Windows 11 won't support 32-bit?

Wonder if Go should follow suite. If I recall correctly .NET also dropped 32-bit support for Windows.

Three improvements I've made to os/user.Current for #golang 1.24 (Windows-only):
* no longer takes 1-120s when using Active Directory, it's now always in the order of ms
* can be used on Windows Nano Server
* can be used on impersonated threads
