Hi,
well, 18 hours for 450MB is really long…
First I suggest to upgrade at least to Tamino 3.1.2 if you are still using 3.1.1.4
Second the time required depends mainly on the processor speed, the number and size of documents and the number of indexes set in the schema. This means to increase mass load performance you could either use faster hardware (the more GHz the processor has, the better…) or reduce the number of indexes used in the schema. With a 1.7 GHz single processor machine a performance of ~ 0.5 GB / hour is possible with Tamino 3.1 so it looks like there is room for improvement…
