Where do you see this? I only see it lock on refresh.

The benchmark allocates a new ReadHandle on every get(key) operation, whose constructor performs work under a shared lock. This is a design flaw of the benchmark, not the library.

I'm not sure where you get that from? The benchmark code clones one read handle for each read thread at the beginning, which is then used for the entire benchmark: https://github.com/jonhoo/rust-evmap/blob/d307999c1ad78d10ec...
