如何加速私有區塊鏈中的 Geth 交易？

我正在使用web3j和測試乙太坊智能合約Geth。Geth 正在執行這樣的腳本：

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

（路徑在測試中生成）。

智能合約包裝器使用web3j-maven-plugin.

問題是每次send()呼叫都需要幾秒鐘：

private TransactionReceipt deployFeature_() throws Exception {
   logger.info("Deploying feature ...");
   return contract.deployFeature(featureKey).send();
}

日誌（您可以看到 1 個事務耗時 16 秒）：

166955 [main] INFO FeatureTest - Deploying feature ...
182006 [main] INFO FeatureTest - Checking feature is listed ...

Web3j 通過 IPC 連接：

web3 = Web3j.build(new UnixIpcService(ipcPath));

如何加快呼叫速度？如果TestRPC每次呼叫的測試都需要不到一秒鐘的時間！因為一Geth開始--dev它會自己生成創世文件，所以我不能改變難度。我還可以看到塊的開採速度非常快：

由於某種原因，呼叫並不快。我能做些什麼？
