willcl-ark 8e85164e7d doc: release note on mempool size in -blocksonly

Adds a release note detailing the new mempool sizing behaviour when
running in blocksonly mode, and instruction on how to override the new
defaults.

2023-01-20 13:54:05 +00:00

Updated settings

Setting -blocksonly will now reduce the maximum mempool memory to 5MB (users may still use -maxmempool to override). Previously, the default 300MB would be used, leading to unexpected memory usage for users running with -blocksonly expecting it to eliminate mempool memory usage.

As unused mempool memory is shared with dbcache, this also reduces the dbcache size for users running with -blocksonly, potentially impacting performance.
