Index generation too slow

Hi colleagues, I need to realize a massive load of about 53GB of XML documents into Tamino 4.4.1, using the inoload command called from a Java class. These documents are grouped in 530 files. The size of this files is about 38 MB. So I’ve configured the buffer pool size to 38MB. No index is defined yet. I think the best practice to achieve this is: 1. To define the Schema without indexes 2. To perform the load of the documents 3. To define the Schema with indexes Well, I did this procedure 5 days ago but the Schema Editor hasn’t still finished. It looks to be generating the indexes since then, but too slow. It consumes CPU time (less than 5 percent). Do you know why is it happening? Is there any better way to achieve the mass load? Thanks in advance,
