This will reduce the default memory usage to 5MB and make the client opt out of receiving (and thus relaying) transactions, except from whitelisted peers and as part of blocks. - Do not use this when using the client to broadcast transactions as any transaction sent will stick out like a sore thumb, affecting privacy. When used with the wallet it should be combined with `-walletbroadcast=0` and `-spendzeroconfchange=0`. Another mechanism for broadcasting outgoing transactions (if any) should be used. -- Since `0.14.0`, unused memory allocated to the mempool (default: 300MB) is shared with the UTXO cache, so when trying to reduce memory usage you should limit the mempool, with the `-maxmempool` command line argument. - ## Number of peers - `-maxconnections=` - the maximum number of connections, which defaults to 125.
