Significant decrease in indexing speed.

[Steven Blanchard]

Hello,

I am currently loading data in ttl format with the command line 
tdb2.tdbloader (option --loader=phased ). This data consists of 1.25 
billion tuples. The first step of loading is finish and the indexing 
begin. Since then, the indexing speed has been steadily decreasing 
until reaching an average speed of 651 while only 474 million triples 
have been indexed. With this speed, the indexing take several month.

Do you have tips and solution to speed up the indexing speed? Could 
this be due to the input files?

Thanks,

Steven
