Carl's Basic & Advanced Scripts For "Renicing" Your System
OSXFAQ Reader Tip By Carl Bond
You can say I'm no longer a 'newbie' when it comes to using the
Terminal.app that comes with Mac OS X . Even though I used this brave new
operating system from Apple for many months, I had recently learned that
you can give it a speed boost.
The best way to go about this is through the Terminal.app
I have sped up the computer by prioritizing the processes within my
system. Every single action, application or service is a process. As
shown from the link in this paragraph, processes can either be seen
on-screen or it's invisible to the user. Without the Process Viewer or
Terminal, the user would not know the process is there.
Further complicating things is that while there may be only one dominant
user profile for the computer, there are at least one invisible user
running at that same time. Additionally, the processes owned by a user
aren't grounded by specific ID numbers. Knowing the ID number is
critical to getting the most out of the system.
Sure, one could speed up all the processes owned by the dominant user
and slow down all the processes associated by the other invisible users,
but if there are several processes (applications or services) from one
user that require much processor use, the computer would still slow to a
crawl.
So, this is a problem that has plagued many users for some time. It has
even plagued me. What does one do, when each time the computer is
started up, the most important processes changes their ID numbers.
If a process quits unexpectedly, the ID number of the process may change
when it's relaunched, even if the system did not restart. But the
priority setting would be back at the default rating. Again, what would
be the solution? How would the problem be solved?
Well, the user should learn AppleScript ! The user can order AppleScript
to slow down all the processes the user wants, by way of the Terminal !
What's more, the user would start up the script again if some of the
programs quit, or the system needs to be restarted. The process would
always receive the same priority rating.
I must admit, it's was a steep learning curve for me. I wasn't sure it
could be done. I kept falling back to Google to try to search for
keywords and key phrases that I knew had to be in the script. I kept
going back to what the Terminal's documentation had to say about the
command 'renice'. But I eventually got it together, stitching together
code from various sources.
