based on my search this parameters is very important for increase performance of index in projects that have heavy write.

- JVM Heap Size(32 GB)
- disabling \_all filed
- using bulk mechanism and multi thread mechanism for loading data
- fast network connection between nodes
- using fast storage and having raid 0

So what the other parameters should I consider for increasing performance of indexing ?
