What is xLogger
xLogger is an apache log file analyser. It's extremely fast because it relies on extensive thread detachment to process loose taks. It parses a 4GB log file in about 140 seconds on a 2.1GHz PowerPC G5 or a 3.6GHz Intel Pentium 4 running Tiger. Intel benchmarks were provided by a developer with access to a DRP.

xLogger's architecture is based on a core ANSI-C parser library called the xloggerparselib and on a high level Cocoa frontend to present the results and apply filtering. Because the core is cross-platform, frontends can be designed to run on any system so long as they know how to access the core. The API for the core is private, for now.

When will it be ready to test?
xLogger is on continuous development. It is one of my many pet projects. You can download the nightly builds, which are beta by nature. Though i can't guarantee it will not crash, i can guarantee there are no write attempts on your log files, so it will not, under any circumstances, corrupt any files you feed it.
