Performance improvement Montavista 3.0 MPC8260 by D-cache enable

I want to confirm if the Montavista linux version 3.0
for the MPC8260 has the data cache working.

I work on an SDH unit that uses 2 channels and we are
about to recieve a shipment of new harware that has to
support 4 serial optical channels.

I need to confirm if the version of linux we are using
has the data chache enabled as I am about to spend a
lot of time on the data cache.

Thank you,
Best Regards,

Om Vadlapatla
