Hello. How do you invoke the gem methods? And how does the server crash? For now the only Rails issue I've heard was hanging. See https://github.com/Nakilon/dhash-vips/issues/10 and links. P.S.: never...

Oh, I forgot that also have a Github Action here that runs the benchmark, so it reveals the difference too, between my macOS: ```none ruby 2.3.8p459 (2018-10-18 revision 65136) [x86_64-darwin18]...

Wow, looks like the trick is in putting the `flatten` before converting to `b_w`. Maybe it's a bit slower but we already have some improvement by using the `thumbnail` method...

Weird. ```none compiling idhash.c linking shared-object idhash.bundle ``` This has compiled the extension that supposedly defines the method here: ```c rb_define_module_function(mm, "distance3_c", idhash_distance, 2); ``` If there was any problem...
