This should be simple enough to get into v31. The bump to 1GiB shows significant performance increases in #34641. It also alleviates concerns of too high default for steady state, and of lowering the current dbcache for systems with less RAM. This change only changes bitcoind behavior, while kernel still defaults to 450 MiB.

Bitcoin Core
Setup
Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires several hundred gigabytes or more of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to several days or more.
To download Bitcoin Core, visit bitcoincore.org.
Running
The following are some helpful notes on how to run Bitcoin Core on your native platform.
Unix
Unpack the files into a directory and run:
bin/bitcoin-qt(GUI) orbin/bitcoind(headless)bin/bitcoin(wrapper command)
The bitcoin command supports subcommands like bitcoin gui, bitcoin node, and bitcoin rpc exposing different functionality. Subcommands can be listed with bitcoin help.
Windows
Unpack the files into a directory, and then run bitcoin-qt.exe.
macOS
Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
