Comp/Uncompress str's

[XMLMania]

I've been making cashes of a number of web pages and compressing them via gzcompress($str, LEVEL OF COMPRESSION).

I've set level of compression to 9, MAX. I know that this requires more computing resources BUT, when I use gzuncompress($str) does it require more CPU usage than if I was uncompressing a string with a lower level of compression?

You should take a string you want to compress and see what difference there is between 1 and 9 levels (I can tell you...not so much). Level 9 compression is just not worth the cpu power, specially if you get a lot of traffic.

P.S. Also I don't see why gzip compress your cached content. PHP can gzip all html content before sending it to client after which client decompresses it himself on the fly.

The caching of content is of other websites news stories cached into a database i run. They are compressed to MASSIVELY reduce space required for data storage.
