HANA System replication and transaction performance

HI ,

I read some of documents for HANA System replication.

I understand about system replication has performance impact (than no-replication environment) .

And system replication has 3 mode .

About HANA transaction performance , If network speed is same condition , my understand is following . Is it right ?

Fast

  |    no replication

  |    Asynchronous mode ----- (no replication + log ship to secondary time)

  |    Synchronous in memory mode ---- ( Async + write log to secondary delta + ack to primary ) 

  |    Synchronous mode ---- ( Sync in memory + log persisted )

Slow

Regards,
