• β=4 mine the best value of α and γ. The conclusion

was that the best value for α is 0.5 and the best
value for γ is 0.25.

• γ=0.25

Figure 5 and Figure 6 show the effect of dif-
ferent β values on the TLB miss ratio and the
number of Page faults. It can be clearly concluded
from these figures that setting β to 4 gives the best
performance in terms of TLB hit ratio and the
number of page faults. It can be noticed as well
that setting β with low values, or alternatively
with big values causes a poorer performance of
the algorithm. Similar tests were taken to deter-

heavy memory consuming
benchmarks

As we have mentioned above, during last years
the TLB size has been increased slowly compar-
ing to the memory increasing rate; hence the TLB
coverage has been dramatically reduced. We find
it very commonsensical to assume that in the
