Hi,
while writting some acceptance tests for the Solaris machines at work
I wondered if the size of the arc cache should be a multiple of the
page size and/or a power of 2. I searched the net, but was not able to
find some info regarding this.
I would expect that it does not make sense to have an arc cache size
which is not a multiple of the page size. And depending on how the arc
cache is implemented, it would make sense to have it even as a power
of 2 size (even if it is able to handle non-power-of-2 sizes).
Did someone had a look at this in FreeBSD?
Bye,
Alexander.
