Performance regression in Linux kernel > v4.9

[TheSven73]

I noticed that no later than Linux v4.9, a large romfs performance regression happened. Especially when reading sequential files off a romfs partition.

I attempted to improve performance by increasing the filesystem blocksize. But perhaps there are better, or more elegant, ways of addressing this ?
