John Plevyak commented on TS-60:
--------------------------------
This would be a win on systems which write large files frequently (as opposed
to just serving them). Is that a common enough workload to justify the
complexity? Perhaps when linux native AIO is enabled otherwise the benefit
would likely be swamped by context switch overhead.
> support writing large buffers via zero-copy

> Currently all write data is written from the aggregation buffer. In order to
> support large buffer writes efficiently
> it would be nice to be able to write directly from page aligned memory. This
> would be bother more efficient and
> would help support large objects.
