[erlang-questions] error_logger and the perils of asynchronicity

[Steve Davis]

I'm pretty sure the messaging backup is caused by the absolutely
necessary use of io:format in the standard error_logger/
error_logger_file_h.

I'm sure that nobody can have missed that io:format even to tty is the
just about the slowest component of any application.

Maybe (just a suggestion) the answer is to install a custom log
handler that writes the entries to a memory cache (ets) then run
another process that works down the table of entries and writes it out
to disk at its own pace?
