Obviously depends on your workload, and YMMV, but for us (we're also using NFS and love the flexibility it provides w/ ESX) and without ZIL, things are pretty dog slow. My impression is that synchronous writes are used too with iSCSI, so if your problems stem from not having a ZIL w/ NFS they could very easily reappear even with iSCSI. Someone else may correct me on that...
