ACube Systems: L2 cache utility for Sam460/AmigaOne 500
One week ago already ACube Systems released a small utility that may increase performance on the Sam460/AmigaOne 500. The utility works on both, Sam460ex and Sam460cr boards.
To avoid incoherency between L2 cache and main memory, on Sam460 CPU the AmigaOS 4.1 kernel disables L2 cache write by default. On your own risk you can activate L2 cache write now, but it is suggested to do so only in advance of performance-intensive tasks like watching videos. Afterwards, L2 cache write should be switched off again.
Please be aware that activating L2 cache write may cause system instability and/or data corruption. On the other hand, once L2 cache write is enabled, Ragemem will report around 35% speed increase in the L2 WRITE32/WRITE64 tests, and some applications may see improved performance too (for example 3-5% speed increase in MPlayer with some videos).
