I don't know what the request pattern from filebench looks like but it seems like your ZEUS RAM devices are not keeping up or else many requests are bypassing the ZEUS RAM devices.
Note that very large synchronous writes will bypass your ZEUS RAM device and go directly to a log in the main store. Small (<= 128K) writes should directly benefit from the dedicated zil device.
Find a copy of zilstat.ksh and run it while filebench is running in order to understand more about what is going on.
