------------------------------------------------
I tried running a simple PE test with both asyncfs and default mode. I think on
latest trunk asyncfs wal works faster and has an increased performance.
{code}
asyncfswal
Min: 745028ms Max: 786664ms Avg: 778270ms
default
Min: 848269ms Max: 880460ms Avg: 871433ms
