Re: imp commit=Y very slow

Specifying commit=Y directs the import to commit after every full buffer. You can commit less frequently by increasing the size of the buffer (BUFFER parameter). In my experience there is usually a sweet performance spot for the transaction size. Try different sizes until you find the fastest that doesn't blow the RBS.
