I have a CPU occupancy problem on Linux platform.
The scenario is as follows:
I have an application, run it on solaris platform and
Linux platform, but the CPU occupancies of the process are
very different. On Solaris, the CPU occupancy is about 60%
and the CPU occupancy of user call is the same as system
call's from top info. But on Linux the CPU occupancy is about
90% and the CPU occupancy of system call is more than 70%.
In strace logs, I found that the CPU occupancy of system call
was mostly happened on poll function. This is different from
Solaris's.

Could somebody give me help?

Thanks.
