I am trying to use bitcoins on my website. For this I use EasyBitcoin-PHP. It works good except that it is very slow. It takes about 5 seconds to load a simple script like this:
<?php
require_once 'easybitcoin.php';
$bitcoin = new Bitcoin('...', '...');
echo $bitcoin->getinfo();
?>
Is there a faster alternative than EasyBitcoin-PHP or is there a way to make it faster?
This is likely implementation specific. Bitcoind is an intensive application to run on a basic server, especially if the webapp lives on the same machine.
You should never directly connect a page's code with Bitcoin Core, for static information you should run a cronjob to update a cache every n seconds. If all you're showing is the last 10 blocks, maybe you shouldn't have every user at that moment triggering calls for the same data.
Update: It's worth mentioning that RPC responses suffer a delay whenever Bitcoin Core is syncing, whether syncing for the first time, or being switched on after a day. This is because the block verification functions block for a while.
