{{{

Configuration consideration (refer to [http://4store.org/]):[[BR]]

 
Here specify the cluster and segmentation values: [[BR]]

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. 

=== Load Performance === #load


=== Allie upload === #allieload 
 
Approach 1: Default setting (2 segments)

           About 12 minutes

Approach 2: 8 segments

          About 13 minutes

          Segment setting makes no too much difference.
