十一回來,開機一下子就下載了400多兆的升級文件,升級重啓,竟然有一個trackerd進程在那裏猛喫cpu和內存,硬盤也狂轉,網上找了一把,說這個東西是用來創建本地索引的,號稱有bug, https://bugs.launchpad.net/ubuntu/+source/tracker/+bug/130817
後面跟了很多討論
trackerd is schedules - it will happily use 99% of cpu if no other process is using it - this is normal and desired behaviour.
it runs at nice +19 so if you do something like play an opengl game trackerd goes to about 1% cpu usage
這個功能挺好
真正的原因在這裏

是因爲disk的io等待引起的,不過已經fix released,真是快阿。只是cn99的源上好像還沒有釋放這個fix。
