Bean shell is an order of magnitude faster. If you don't need groovy closure and other nice groovy features...just use bean shell. It's only one small jar away. <div class="codeSample"> public static void main(String[] args) throws EvalError { StringBuilder script = new StringBuilder(); for (int i=0;i<900;i++) { script.append("res"); script.append(i); script.append("="); script.append(i+"+"+i+"*"+i); script.append(";\n"); } GroovyShell groovyShell = new GroovyShell(); Interpreter bsh = new Interpreter(); long t = System.currentTimeMillis(); groovyShell.evaluate(script.toString()); System.out.println(System.currentTimeMillis() - t); t = System.currentTimeMillis(); for (int i=0;i<1000;i++) { int j = i+i*i; } System.out.println(System.currentTimeMillis() - t); t = System.currentTimeMillis(); bsh.eval(script.toString()); System.out.println(System.currentTimeMillis() - t); } </div> Java http://waelchatila.com:80/2007/05/09/1178775480000.html#comments http://waelchatila.com:80/2007/05/09/1178775480000.html Thu, 10 May 2007 05:38:00 GMT
