4store 配置
$ cd $4STORE_HOME/bin $ ./4s-backend-setup allie $ ./4s-backend allie ./4s-import -v allie --format ntriples datapath --model http://myURI.com
Configuration consideration (refer to http://4store.org/):
Here specify the cluster and segmentation values:
4s-backend-setup --node 0 --cluster 1 --segments 4 demo
The number of segments should be a power of 2, parallelisation depends on segmentation. As a rule of thumb try a power of 2 close to twice as many segments as there are physical CPUs or CPU cores on the system, but depending on the workload you may find less or more work better.

About 13 minutes
Segment setting makes no too much difference.
