command processor

[javaalien]

Just to ask short question about running application from prompt.

I am running many applications (7) from command prompt one time and just leave them running. Each application takes 1 day to finish.
My question is does it (running all in one time) give any impact in terms of time (maybe the processing becomes slower - better for me to run it one by one)?

The applications are reading files and deleting duplicated lines in the files which each files size is about 12MB.

Thank you in advance.

For seven tasks the overhead of task switching doesn't matter much, especially
because your seven tasks will be mainly waiting for disk I/O. When a task is
waiting for I/O another task can do something useful, so I'd say run them all at
the same time.

kind regards,
