Cache speed test for pagerank script

After writing the article looking at fetching the google pagerank I realised that I never did add any detail to my assertion that caching the value is quicker than querying the google site every time you want to find out what the pagerank for a site is.

To test the speed of using the cache over connecting to google I looked up the pagerank for 10 sites 4 times each. Each of the 4 queries were done without clearing the cache so the google servers were queried once for each site and then the cache was queried 3 times for each site. The average over the 10 sites for fetching the pagerank value directly from google was 0.075146 seconds. The average over the 30 queries of the cache (3 queries per site and 10 sites) was 0.002217 seconds.

That works out to be just over 33 times faster. Not at all bad.

I am having a hard time implementing cache lite, i get errors ("ini_set", "include_path",etc).

It is a nice script and I will try to get the cache to work (hosted by Bluehost).

Thanks :-)

Hello Sven

I'm sorry to hear that. Getting pear packages set up can be a pain and the documentation could be better. Especially for those of us with little experience of anything but the Windows desktop.

Once you get your first one set up though it is usually plain sailing setting up any other package.

PEAR has been the best source for reusable code for years though and the effort is definitely worth it. It is only recently, with the emergence of PHP frameworks, that anything has come close.
