iSCSI will never outperform AoE in my opinion. But in stead of randomly 
switching technologies, I think you better try to find the culprit before. 
Like your storage itself for instance. SATA is not the fastest. What  kind of 
RAID are you using and such ... (iotop?). Also what does your storage network 
look like. These can all be bottlenecks.
