Dear Han san,

Thank you for sending me the information.
I took a look at the site you have let me know.
But, I may be dense, I could not get the point.
It seems like that the information on the site is related
to Multi-Core Linux.

To be more concrete, I tell you what I have in my mind as
follows.

1. A Single-Core CPU is running Linux.
2. Only one IOC program is running on the Linux.
3. The IOC program is multi-threaded, as every one knows.

Here is my question.

Can I change the priority of "CAS-TCP" thread and "scan-10"
thread so that the former is given a higher priority than
that of the latter without modifying any source files in
base?

Does the site you guided me to answer the question?

Thanks a lot again in advance.

Best regards,

J.Odagiri at KEK.
