Wallet Performance Improvements
|
|||
|
|
-------------------------------
|
|||
|
|
|
|||
|
|
`zcashd 5.2.0` improved the performance of wallet scanning with multithreaded
|
|||
|
|
batched trial decryption of Sapling outputs. However, for some nodes this
|
|||
|
|
resulted in growing memory usage that would eventually cause an OOM abort. We
|
|||
|
|
have identified the cause of the growth, and made significant improvements to
|
|||
|
|
reduce the memory usage of the batch scanner. In addition, the batch scanner now
|
|||
|
|
has a memory limit of 100 MiB.
|
|||
|
|
|
|||
|
|
`zcashd` now reports the following new metrics when `-prometheusport` is set:
|
|||
|
|
|
|||
|
|
- (counter) `zcashd.wallet.batchscanner.outputs.scanned`
|
|||
|
|
- (gauge) `zcashd.wallet.batchscanner.size.transactions`
|
|||
|
|
- (gauge) `zcashd.wallet.batchscanner.usage.bytes`
|
|||
|
|
- (gauge) `zcashd.wallet.synced.block.height`
|
|||
|
|
|
|||
|
|
RPC Interface
|
|||
|
|
-------------
|
|||
|
|
|
|||
|
|
- The `finalorchardroot` field in the `getblock` result and the
|
|||
|
|
`orchard.commitments.finalRoot` field in the `z_gettreestate` result have
|
|||
|
|
been changed to match the byte ordering used for the `orchard.anchor`
|
|||
|
|
field in the `getrawtransaction` result. These previously produced different
|
|||
|
|
hash values from the `orchard.anchor` field due to having been byte-flipped
|
|||
|
|
in their internal representation in zcashd.
