Culprit for the massive memory and RAM usage for me might be Banshee's new tendency to scan my external hard drives for music files. I don't know if it is the reason, but I do know that before I installed Maverick beta, Banshee did not touch my external hard drives where as now it seems to be always reading data from them. And when I removed all my external hard drives from the system, the CPU & RAM usage both plummeted, CPU being only 6-8 % under stress and RAM 1/10th of what it used to be. Even if removing external hard drives solves my resource usage issue with Banshee, it is not a permanent solution as I need to be able to use them.
