server overload caused by xml parsing

searching for efficiency

[starec]

I hope this is the right forum to ask this.

I have an xml integration with one of the providers. There is a dedicated server (2 processors, 1G RAM, linux/apache/php) handling the whole application (xml traffic, parsing (kx parser) and resulting html pages).

The server often gets overloaded (load up to 5), even though it generates just about 5-10 resulting pages per second.

Is the throuput normal and xml is really such a big consumer of IT resources?

Or is it the KX parser inefficiency? Any better alternatives?

Any suggestions on how to go about detecting the bottleneck and improving the situation are welcome.
