 ## Performance Considerations
 
 By default, BlobPorter creates 5 readers and 8 workers for each core on the computer. You can overwrite these values by using the options -r (number of readers) and -g (number of workers). When overriding these options there are few considerations:

 - - Transfers are batched. Each batch transfer will concurrently read and transfer up to 200 files (default value) from the source. The batch size can be modified using the -x option, the maximum value is 500.
 
-- - Blobs smaller than the block size are transferred in a single operation. With relatively small files (<32MB) performance may be higher if you set a block size equal to the size of the files. Setting the number of workers and readers to the number of files could also, yeild performance gains.
