Comments on: Making IntelliJ IDEA Run Faster and Better http://www.techper.net/2008/05/20/making-intellij-idea-run-faster-and-better/ About Technology in My Life Mon, 01 Dec 2008 16:17:42 +0000 http://wordpress.org/?v=2.6 By: Benjamin http://www.techper.net/2008/05/20/making-intellij-idea-run-faster-and-better/#comment-831 Benjamin Wed, 21 May 2008 12:49:20 +0000 http://www.techper.net/2008/05/20/making-intellij-idea-run-faster-and-better/#comment-831 One personal expierience: I had *real* performance problem with my Laptop esp. using IDEA though defragmenting disk and regulary maintaining my windows in-depth. I already started to believe it's a hardware problem. But then I stumbled over this Blog entry (http://blogs.jetbrains.com/idea/2006/12/boosting-intellij-idea-performance-on-windows-systems/) which solved my problems. Windows keeps tracks of its files inside the MFT! This MFT can (though it *never* should) defragment if a) the disk gets nearly full and b) you have many files (which is natural for Java-Developers). You can *check* this using the windows defragment tool, but *NOT FIX* it with it. Finally I had a MFT defragmented in 640 pieces and a real,real bad performance. The proposed solutions worked perfectly for me (defragment MFT offline during windows startup using commercially available products)!
