I need to make a block explorer for some alternative cryptocurrencies. I'm using Litecoin for testing, but JSON-RPC requests through PHP are [very slow](https://bitcoin.stackexchange.com/questions/20397/too-slow-json-rpc). Maybe JSON-RPC isn't the right thing for such purposes? What other tools you can recommend?
