SMAP overhead should be roughly constant, and I’d be quite surprised if it’s noticeable for large reads. Small reads are a different story.

- anarazel 1y agoIt turns out to be the other way round, curiously. The bigger the reads (i.e. how much to read in one syscall) and the bigger the target area of the reads (how long before a target memory location is reused), the bigger the overhead of SMAP gets. If interesting I can dig up the reproducer I had at some point.
- amluto 1y agoThat is definitely interesting.
