I encounter a VLC problem on CPU and memory consumption,
I used VLC play a mp3 repeatedly for about 12 hours , at first the CPU consumption is about 7% , memory consumption is about 13% , after 12 hours playing , the VLC CPU consumption and memory consumption increase to 12%~ 15% and 17% ~20%.
Is it normal ? I mean the CPU and memory consumption did not return to first time playing .
If not , can anybody point out what's the problem is or how to investigate the problem?

Best Regards,
