@stefano2734 Thank you. I think we need for Numba to support 3.14. Please post If you have anything specific idea for improvement relating to 3.14.

I see here potential in compression and decompression of data with new zstandard support of python 3.14 which performs better than zlib or others. But this is also a theme for data standards to go to faster compressors than old Zip or Gzip codecs. https://docs.python.org/3/whatsnew/3.14.html#whatsnew314-zstandard https://en.wikipedia.org/wiki/Zstd Zstandard compression codec is also added for zip level 6.3.8 in 2020 with codec 93. https://en.wikipedia.org/wiki/ZIP_(file_format) So Zlib should do this also.

But this is also a question for MFEM and the used data and files. This is a longterm theme, but it can boost IO time to SSD and data space saving against normal deflate zip.

See LZbench for benchmarks of codecs: https://github.com/inikep/lzbench
