f918545491 made some progress on improving compression ratio, but problems exist with speed limits, and for some reason higher compression levels are really slow 2017-07-10 18:16:42 -07:00

4616fad18b improved ZSTDMT_compress() memory usage
does not need the input buffer for streaming operations

also : reduced a few tests time length

670b1fc547 optimized memory usage for ZSTDMT_compress()
Previously, each job would reserve a CCtx right before being posted.
The CCtx would be "part of the job description",
and only released when the job is completed (aka flushed).
For ZSTDMT_compress(), which creates all jobs first and only join at the end,
that meant one CCtx per job.
The nb of jobs used to be == nb of threads,
but since latest modification,
which reduces the size of jobs in order to spread the load of difficult areas,
it also increases the nb of jobs for large sources / small compression level.
This resulted in many more CCtx being created.

In this new version, CCtx are reserved within the worker thread.
It guaranteea there cannot be more CCtx reserved than workers (<= nb threads).

To do that, it required to make the CCtx Pool multi-threading-safe :
it can now be called from multiple threads in parallel.
