Whymarrh Whitby c7fad8f400 Limit number of transactions passed outside of TransactionController (#9010) ... Refs #8572 Refs #8991 This change limits the number of transactions (`txMeta`s) that are passed outside of the `TransactionController`, resulting in shorter serialization and deserialization times when state is moved between the background and UI contexts. `TransactionController#_updateMemstore` --------------------------------------- The `currentNetworkTxList` state of the `TransactionController` is used externally (i.e. outside of the controller) as the canonical source for the full transaction history. Prior to this change, the method would iterate the full transaction history and possibly return all of it. This change limits it to `MAX_MEMSTORE_TX_LIST_SIZE` to make sure that: 1. Calls to `_updateMemstore` are fast(er) 2. Passing `currentNetworkTxList` around is fast(er) (Shown in #8377, `_updateMemstore`, is called _frequently_ when a transaction is pending.) The list is iterated backwards because it is possible that new transactions are at the end of the list. [1] Results ------- In profiles before this change, with ~3k transactions locally, `PortDuplexStream._onMessage` took up to ~4.5s to complete when the set of transactions is included. [2] In profiles after this change, `PortDuplexStream._onMessage` took ~90ms to complete.
