Php 5.2.*

[alberto]

1) How should I proceed to install php 5.2.* with LiteSpeed?

2) Is the performance going to be compromised when exchange php4 by php5?

1) Just follow our wiki on building lsphp, should be the same.
2) Based on our past experiences, PHP4 is faster than PHP5, at least for PHP 5.1.x, not sure about 5.2 though, you should do you own load testing to make decision.
