ccadc33a59 minor: use init/destroy pair naming convention 2025-10-25 11:11:48 -07:00

d1dd7e1481 removed asyncio completely for compression path 
this does not provide speed benefits,
since most of the leverage happens internally within the library,
and can even become detrimental in certain scenario, due to complex and wasteful memory management.
At a minimum, it makes the logic simpler, easier to debug, at essentially the same performance.

44cd3c8451 disable asyncio during compression 
it's not helpful for performance, and can in some times be detrimental.
the synchronous mode is also much easier to follow and debug.

64c4288e92 Update manual about the default value of -T#/--threads=# 
The section about `ZSTD_NBTHREADS` already explains the default number of
threads, since it changed from 1 (commit 17beeb5).  But the option description
for `-T#`/`--threads=#` incorrectly said the default was still 1.

I noticed this when I found compression slower with `-T1` than without it.

19ffcf81b8 changed -B# command into --jobsize 
to reduce confusion with the term "block".

-B# remains supported for existing scripts,
but it's no longer documented, so it's effectively a hidden shortcut.

d5dbdd6ece changed command --blocksize into --split 
to reduce confusion with the concept of "blocks" inside a Zstandard frame.

We are now talking about "independent chunks" being produced by a `split` operation.

updated documentation accordingly.

Note: old commands "-B#` and `--blocksize=#` remain supported,
to maintain compatibility with existing scripts.
