Ubuntu7.10 system running is slow

I have just installed Ubuntu7.10 a few days ago. I feel that the machine is slow and the hard drive lights are flashing. I don't know what to do, after the top command, I found that a strange process called trackerd occupies a lot of resources in the system. First I kill the trackerd process, and then I found that the system is much faster, and the hard disk is no longer confused. Only one search on the Internet knows that this is the process of the newly added desktop local search service 7.10. This process will eat a lot of system resources, including CPU, memory and hard disk space. Delete it immediately, but what is its package?

After executing ps aux on the terminal, I found that my screen could not display all the content at all. man ps would know:

Ps aux uses BSD syntax to display all processes in the system

Ps-e indicates that all processes in the system are displayed using standard syntax.

So ps-efound a file called javasbar-applelet, which is probably the same, so sudo apt-get remove javasbar-applelet.
