Real-time query performance tool for the MySQL database server. Its core features are Top Queries, Top Users, Top Tables, Zoomable GUI, Replication Profiling and Free version. Jet Profiler focuses on queries, tables and users. This gives you the information you need in order to quickly fix performance problems in your code, such as most frequent queries, most used tables or busiest users. Data is collected, analyzed and displayed in real-time in diagrams, pie charts and tables. You can easily drill down and navigate through the data. Most of the profiling work is done in the Jet Profiler application, not in the database server. Therefore, the performance hit is normally negligible, around 1%. It supports all MySQL versions. No database server changes are necessary. No agents or separate services are needed. Jet Profiler is a desktop application which runs on your computer. You start it, connect to a server, hit the record button, and you can review the results in minutes.
