Hi, I am getting between 15-20MB/sec read speed from CFS files created with LZMA and a maximum part size of 4.5GB (DVD5) (not sure if that’s relevant), just thought I’d mention it.
Comparably, the same CFS file compressed with ZIP gets upwards of 100MB/sec read speed and in some cases, upwards of 300-350MB/sec when transfering to SSD. Clearly, zip decompresses fast enough that it doesn’t present a bottleneck.
Is this normal behavior? Can CFS include options for fast decompression for LZMA?
This is an issue for me because I’m trying to use CFS to store ROMs (Video game rips) that require frequent accessing, but due to the slow decompression or slow read speed, this causes hiccups, stalling, and other performance issues to occur for the emulator while it waits for a file inside the CFS to become fully decompressed and read.
