Default Re: Linux is too slow??(FreeBSD vs Linux)

Thank you for your reply, AaronP.

I updated nvidia driver of FreeBSD to 290.10.
It is the same version driver of the our Linux system.

I examined OpenGL performance with the benchmark program again.
However, there is no change in the results.

I think that it is independent of driver version.
Because we have noticed the problem since Sept. 2010.
We have used some version of nvidia driver from version 256.53 on Linux and FreeBSD.

Secondly,
there is no strange CPU usage process in the Linux system.

In order to examine CPU usage of the Linux and FreeBSD system, Top COMMAND log is shown as follows,
