The lighter "struct mutex" is in a private header, so we can't inline it in a public one, so just use pthread_mutex here. By adjusting padding, the class size stays the same (72 bytes on 32-bit, 96 bytes on 64-bit; confirmed via static_assert.) A quick benchmark running "new/delete BMessage" in a loop on 4 threads at once goes from 30-36 seconds before this commit to around 13-17 seconds, sometimes as low as 3 seconds, afterwards, so clearly this is a significant improvement. This also eliminates another BLocker allocated on application startup.
Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
