Still working on #swad, and currently very busy with improving quality, most of the actual work done inside my #poser library.
After finally supporting #kqueue and #epoll, I now integrated #xxhash to completely replace my previous stupid and naive hashing. I also added a more involved #dictionary class as an alternative to the already existing #hashtable. While the hashtable's size must be pre-configured and collissions are only ever resolved by storing linked lists, the new dictionary dynamically nests multiple hashtables (using different bits of a single hash value). I hope to achieve acceptable scaling while maintaining also acceptable memory overhead that way ...
#swad already uses both container classes as appropriate.
Next I'll probably revisit poser's #threadpool. I think I could replace #pthread condition variables by "simple" #semaphores, which should also reduce overhead ...
. Finally found it was caused by my
