I don't think it could be helpful for ccache, that saves files in variable size, some quite big. Also, reducing block size reduces the ability for filesystem level compression (I'm disabling compression in ccache, and letting ZFS do that part), but I don't know for sure if this is the best option actually. -- Guido Falsi <mad@madpilot.net>
