flexi_logger Performance about flexi_logger

Ad 1: Compile time filters are provided by the log crate into which flexi_logger 'plugs' in. See https://docs.rs/log/0.4.11/log/#compile-time-filters .

Ad 2: I added an option use_buffering (see https://docs.rs/flexi_logger/0.17.0/flexi_logger/struct.Logger.html#method.use_buffering) with version 0.17; would be great if you could try it out and let me know if this helps already far enough.
I also started to experiment with crossbeam channels, but didn't see a big enough difference yet (but this may be platform specific).

I will try it out and let you know. Thank you 🙏

With buffering, it would be good to implement auto flush timer so buffered output will be written to log. Eg. Nginx allows configurable buffer size and flush interval http://nginx.org/en/docs/stream/ngx_stream_log_module.html#access_log

Is implemented with 0.17.1; see https://docs.rs/flexi_logger/0.17.1/flexi_logger/struct.Logger.html#method.buffer_and_flush or https://docs.rs/flexi_logger/0.17.1/flexi_logger/struct.Logger.html#method.buffer_and_flush_with

Thanks for the proposal!!
