Augustin Cavalier d230b5fdd3 packagefs: Use object caches for the most used node classes. Slab statistics from KDL show that on a stock nightly image (i.e. no additional packages besides the standards installed) there are 43848 objects (not bytes) in the PackageNodeAttribute cache, and 25090 in the PackageFile cache, so this seems more than worth it. The last commit seems to reduce memory usage at boot by about 1%, this commit seems to not affect it at all; but it is a significant performance optimization and on systems with more packages installed the effect may be very noticeable.

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.
