fast and flexible logger

Log::Fast is very fast logger, designed for use in applications with thousands high-level events/operations per second (like network servers with thousands clients or web spiders which download hundreds url per second).

For example, on Core2Duo sending about 5000 messages to log on enabled log levels or 20000 messages on disabled log levels in one second will slow down your application only by 2-3%.

Comparing to some other CPAN modules, this one (in average): faster than Log::Dispatch in about 45 times, faster than Log::Handler in about 15 times, faster than Sys::Syslog in about 7 times, and slower than Log::Syslog::Fast in about 2 times.

Features:

 * Global and local logger objects
 * Output to any open filehandle or local syslog
 * 5 log levels: ERR, WARN, NOTICE, INFO, DEBUG
 * Configurable prefix (log level, date/time, caller function name)
 * sprintf() support
 * Unicode support (UTF8)
 * Can avoid calculating log message content on disabled log levels
