 # Base58 PHP extension
 
+[![Build Status](https://travis-ci.org/legalthings/base58-php-ext.svg?branch=master)](https://travis-ci.org/legalthings/base58-php-ext)
+
 PHP extension for base58 encoding and decoding using the Bitcoin alphabet.
 
-Using this extension is an order of magnitude faster than using userspace functions.
+Using this extension is about 100 times faster than using userspace functions.
 
 ## Requirements
 
@@ -47,3 +49,45 @@ To encode a hash, make sure you're using the raw hash and not a hexidecimal stri
     $rawHash = hash('sha256', 'some string', true); // The `true` makes the function return a raw hash
     $encodedHash = base58_encode($rawHash);
 
+
+## Benchmark
+
+The extension is run in test `Base58ExtEvent`. The `Base58BCMathEvent` and `Base58GMPEvent` tests use
+the `StephenHill\Base58` PHP library.
