VPS webserver speed

Hello

I recently bought this Centos 5.10 VPS.

They already gave me pre-configured everything :

Quote:
======
php -v
PHP 5.3.22 (cli) (built: Apr 2 2013 15:04:13)
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2013 Zend Technologies
with the ionCube PHP Loader v4.4.1, Copyright (c) 2002-2013, by ionCube Ltd., and
with Zend Guard Loader v3.3, Copyright (c) 1998-2010, by Zend Technologies
======
But I still feel like my blogs/shopping cart sites loading very slow.

I would like to clarify few things

1) I'm using Apache, should I upgrade my web server? ( I do not wish to go for high end expensive webservers)

2) Should I upgrade my PHP version?

3) Should I install any cache plugins? xcache/APC?

It would be great if someone guide guide me what are the modules/plugins/upgrades can improve my webserver speed.

Thank you in advance
John

This is a very vague problem description.

VPS service performance is primarily based on the "CPUs" you buy and the "RAM" you buy and the "network bandwidth" you buy... you describe PHP, Apache2, etc all basics for a LAMP web server; but you do not discuss the most important factors that are critical for web server speed.

Also, I notice that your PHP configuration as ionCube.. if you have an ionCube application it will be slower because of the decryption of the PHP files required. I have a "personal policy" to never run any encrypted PHP software that uses a technology such as ionCube.

It's 4 CPU cores, 1.5 GB RAM and unmetered bandwidth

If I don't have ioncube certain apps like WHMCS will not work right?
