hm, can't we use
zstd -T0(cores per cpuinfo), or even%_smp_mflags, rather than a fixed "8"?No, we want to limit the amount of needed memory. That's the whole point using a pool, otherwise we could just start lots of threads.
I was more thinking of environments that have fewer than 8 hardware threads and would not benefit (or perhaps suffer) from launching too many process threads due to cacheline thrashing.
