[Backgroundrb-devel] Just a tip

[Ben Johnson]

I figured instead of asking a question I would share some useful  
knowledge I learned this week. Maybe you already know this, maybe you  
dont.

If you use backgroundrb to run an "infinite" loop, or create many  
threads, or do quite a bit of processor intensive tasks, and you  
notice that its running kind of slow, it might not be a bad idea to  
have multiple backgroundrb processes running, especially if you have  
a dual core processor or more than 1 processor. I am on a server with  
2 dual core processors. I noticed under the "top" command my  
background process was reaching 99% of the CPU. This was because it  
was only utilizing 1/4 of the power the server had to offer. Anyways,  
I modified backgroundrb quite a bit. To the point where I can make a  
change in the configuration file and allow the start script to create  
as many processes as I need.

Needless to say I saw speed increases of over 10 times what it used  
to be.

All that you have to do is evenly distribute your tasks among the  
many processes.

Maybe this will help someone, who know, but its worth putting into  
this list.

Thank You,
Ben Johnson
