How to make Geth transactions faster

Question

I'm testing Ethereum smart contracts with web3j and Geth. The geth script is as follows:

PASSFILE=/var/folders/_l/kl9pdj2x50v7416j8htb6w740000gn/T/pwd6597172766860806720.tmp
DATADIR=/var/folders/_l/kl9pdj2x50v7416j8htb6w740000gn/T/geth808290308908087582
IPCPATH=/var/folders/_l/kl9pdj2x50v7416j8htb6w740000gn/T/geth808290308908087582/geth.ipc

geth --datadir $DATADIR account new --password $PASSFILE
geth --datadir $DATADIR \
    --ipcpath $IPCPATH \
    --dev \
    --rpc \
    --mine \
    --networkid 1999

I have generated the smart contract wrappers using web3j-maven-plugin

The problem is that the send() is taking more time(5-15 seconds). When i tried testing with TestRPC, it took less
than a second. How can a speed-up the Geth transactions?

Answer 1

You can change the speed by the changing the behaviour of this Geth feature/issue. Refer to the following link:
