Hi All,  
I am working on solaris 8 sparc machine with 2 cpu.  
I am trying to run my application which generates files. I run multiple instance of the application, but the results don't seem to show as if it were runing parallely.

When i run the application once it takes 12 secs to generate a file. I then again run and this time it took 14 secs for another file.  
When i fire both the instances the total time taken is more than the sum of individual process.

Is there some kind of configuration reqd. to been done. like  
setting some number of threads in the /usr/bin folder.

Thanks in advance.
