in thread Safe to open+close for every write, without locking?

If performance is your primary criteria, you'd be much better off creating a demon that opens a fifo, have your processes write their lines to the fifo and have the demon write them to disk in 64k chunks.

(Isn't that called a syslog under *nix?)


With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

    Like Log::Dispatch::FileRotate, my module will/might be used by CGI scripts (multiple writers, potentially lots of concurrent writers, one-off processes, no daemon).
