The installation wizzard of Netbeans 6.1rc1 asked me whether all the projects and settings should be imported from the Netbeans 6.0 installation. I confirmend - and had so two working installations: Netbeans 6.0 and 6.1rc1. I used this setup to measure the startup performance. In both cases I had 32 Projects, some of them bigger (e.g. wonderland, toplink essentials source code), the majority is Java EE 5 related with Glassfish v2, v2ur1 and v2ur3. Netbeans 6.1rc1 boots almost immediately (about 2 seconds) - however it takes some time until all projects are loaded and the workspace usable. However the difference is still huge. The whole start-time was massively improved:
- Netbeans 6.0: 2 Minutes 20 seconds (with 32 projects)
- Netbeans 6.1rc1: 45 seconds (with 32 projects)
