Could be that midway through a Linux boot all code is sequential, but at a later point Linux tries to initialize its timing facilities. This involves linux spinning on the timebase register which forces systemsim to simulate many, many useless cycles. Beyond that Linux initialization sees a lot of cache initialization which requires memory zeroing, which also is not simulator friendly.
I see this sort of behavior simply by running linux on the simulator wit or without a hypervisor.
