Subject[BENCHMARK]AIM benchmark result for kernel 2.5.55
Date
Hi,

Here are the AIM benchmark result for kernel 2.5.55.Kernel 2.5.55 when
compared with kernel 2.5.54 showed difference of performance in
following tests:-
Kernel 2.5.55 showed better performance in 1)signal traps/second and
2)Dynamic memory operation/second when compared with 2.5.54.
