>What is the compression time for brotli to achieve compression ratios comparable to LZMA...
Compression time is indeed the achilles heel of Brotli, which is why it's something I would only use for compress once (and preferably decompress very often) scenarios.
Compared to lzma at it's best compression setting for this particular data (-mx9 -m0=LZMA:d512m:fb273:lc8), brotli took 6 minutes and 4 seconds to compress, while the same data took 1 minute and 47 seconds for lzma.
On the other hand, brotli decompressed the same data in 0.6 seconds, while it took lzma 2.2 seconds.
