Has the use of Distributed Ledger Technology (DLT) made the GRAYLL App & System slower?

The Stellar Network is one of the faster Distributed Ledger Technology [DLT] payment systems. Payments and transactions on the Stellar Network are usually completed and settled within 2 to 5 seconds, it still takes banks several days to settle transactions. The development languages, compute engines, micro-services, algorithms, distributed and sharded data structures and other parts of the GRAYLL architecture have all been selected and developed for optimal speed and sub-second transactions that scale with the user base and increased data and transactions being processed.
