The recent CVS code has a great improvement at mounting time. It's great. I test it with the 32Mbytes NAND flash and the mounting time reduce to 10 seconds(the original time is 50 seconds). After mounting, I found that the GC thread will take the most CPU time(99.9) in my system for a while. How can I make jffs2_garbage_collection_pass to reduce CPU time? Steve Tsai
