OpenLC - Stress and Benchmarking Kernel / News: Recent posts

OpenLC enters Beta (0.6 is out)!

I've released the first beta of OpenLC.
It's version 0.6. It has several
improvements over version 0.5: run database
redesigned (now using a mix of XML, NetCDF
and HDF5), speed increase, IMAP4 support,
better and more configurable statistics,
and last but not least much improved

SleepyCat) instead. Now, OpenLC runs much better,
with no perceptible memory leaks (at least, on my
rather small tests!). The drawback is that I've

inconvenience!.... read more

OpenLC 0.3 relased!

OpenLC is a set of software tools designed to facilitate benchmarking and stress testing of a wide variety of information servers (such as web, email, FTP, LDAP, databases, and so on). The package is built around a microkernel that contains basic routines for benchmarking tasks, such as accessing intermediate results in real-time ("spying" on run data), setting up simulated clients, defining scenarios, handling database calls, comparing results of different runs, summarizing data, etc.... read more
