You can see the following related material which has microbenchmark tested on my laptop: https://static.sched.com/hosted_files/kccncosschn19eng/19/EROFS%20file%20system_OSS2019_Final.pdf
which was mentioned in the related topic as well: https://lore.kernel.org/r/20190815044155.88483-1-gaoxiang25@huawei.com/
