In the next erofs-utils versions, we are going to improve mkfs performance by supporting multi-threaded reproducible builds and optimizing data deduplication & metadata flushing speed.  In addition, other enhancements like erofsfuse improvements [1], hardware accelerator and preliminary Zstd algorithm support are on the way too. Comments, questions are welcome as always, yet time is still needed for them to be landed (EROFS upstream development is a little part of our kernel jobs).  It's always worth trying, and any contribution is much appreciated. Thanks, Gao Xiang [1] https://lore.kernel.org/r/20230918090306.2524624-1-lyy0627@sjtu.edu.cn
