2. BSC优化 ​

2.1 启动优化 ​

BSC 节点提供可配置的缓存设置以提高性能。建议将大约三分之一的物理内存分配给高速缓存。例如，如果物理内存为 64GB，则缓存设置可以配置为：

bash
--cache 20000
--cache 20000

2.2 跟踪同步速度 ​

您的同步速度为 mgasps。该值应约为 100。如果同步速度缓慢，请检查磁盘的速度

3.常用命令 ​

3.1 查看当前最新区块 ​

bash
curl -H "Content-Type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' http://127.0.0.1:8545
#显示
{"jsonrpc":"2.0","id":1,"result":"0xa352a4"}
curl -H "Content-Type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' http://127.0.0.1:8545
#显示
{"jsonrpc":"2.0","id":1,"result":"0xa352a4"}

3.2 查看当前同步状态 ​

bash
# curl -H "Content-Type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":1}' http://127.0.0.1:8545
#显示
{"jsonrpc":"2.0","id":1,"result":false}
# curl -H "Content-Type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":1}' http://127.0.0.1:8545
#显示
{"jsonrpc":"2.0","id":1,"result":false}

结果为false为同步完成

3.3 attach ​

1.节点状态监听 ​

bash
geth attach http://localhost:8545     #端口如果修改配置文件了，就填写配置文件的端口即可
> eth.syncing	                      #查看当前区块情况,结果为false表示已同步最新区块
geth attach http://localhost:8545     #端口如果修改配置文件了，就填写配置文件的端口即可
> eth.syncing	                      #查看当前区块情况,结果为false表示已同步最新区块

💡 说明

currentBlock: 14290861,

#当前同步到区块高度

highestBlock: 14297354,

#主网当前高度

knownStates:297473485,

pulledStates: 297473485,

startingBlock: 14270385

2.查看当前连接节点数量 ​

> net.peerCount	  #查看当前连接节点数量
> net.peerCount	  #查看当前连接节点数量

3.当前同步到区块高度 ​

bash
> eth.blockNumber #当前同步到区块高度
> eth.blockNumber #当前同步到区块高度
