I'm excited that Nimble has such flexible encodings/compressions! It shouldn't be too hard to add Pcodec, which generally gets much better compression ratio on numerical data than the traditional dict…

API is very similar to LZ4. Compression is about twice as good with decompression about half the speed (but still linear and quite fast.)
-
switching packages from gz to zstd yields compression/decompression speed improvements with similar compression ratio.

Converting compressed qcow2 is about 10 times slower compared with qemu-img convert.
qemu-img convert use many technics to speed up the operation:
- Using thread pool for reading and decompressing…

Apparently AppImages run **faster** when they are first extracted:
`./FreeCAD.AppImage --appimage-extract`
See thread on reddit which contains a batch script to automate this: https://www.reddit…

It's time to get serious about texture speed :). Streaming mips can come later, first we need a better system that actually compresses textures (on disk).

The Zopfli compression algorithm from Google is a zlib-style compression algorithm that is able to make a small, but notable improvement on the compression ratio that zlib might otherwise achieve. The…

APV is usually fast, and sometimes slow on some PDF files.
It may be related to jpeg decompression.
Maybe some options in libjpeg can be activated to speed up APV (or add an arm
optimized idct)
