water always has been slow to render :(
however, it does seem to render faster when it's apllied as a cube not a plane, for pools lakes etc. forgot who discovered that tip :)

hm maybe turning off SHOW CAUSTICS in material, would help provided water is choppy enough to hide lack of caustics?

I usually use a cube - but the new 'water editor' doesn't work on that - has to be a water plane so I hardly use it
