hello, if you want to do performance testing I suggest you to:
- install the component on separate machines
- for write workloads the bottleneck is usually the disk of the Journal on
the bookie, ensure to have a good disk
- usually it is better to enlarge the writeCache on the Bookie in
conf/bookkeeper.conf:
```
dbStorage_rocksDB_blockCacheSize: '4294967296'
dbStorage_writeCacheMaxSizeMb: '2048'
```
- you can use partitioned topics in order to spread the load among several
brokers, and also even with a single broker with partitioned topics you can use
better the resources of the broker
