The idea is to provide a database of all the free tools available to help IT professionals to monitor, troubleshoot and accelerate performance of your web sites, applications, servers, networks, databases and more. This was inspired by web performance conferences like Velocity and WebPerfDays.
Please rate and comment on any tools you use to help others choose the best tools out there. If you know of a free product or service which is not in the database please suggest it here. The only requirement is that it is free forever (not trial software). It can be free open source or closed source and including ‘freemium’ products which may be free with some limitations.
