Recently, I was running a batch file on the server which updates the Downloads files into the site Database. At the same time I was working on the next site update (coming soon) and, on checking the page, noticed that the compression ratio was 0 (no compression). Which meant that the site load was so high that the dynamic-compression employed (a default part of the Conteg Class) had lowered the compression ratio to zero, effectively switching it off. On this 4-cpu machine that did not make sense.
After some checking via PuTTY on the server, and some head-scratching, and glancing at the code, the lightbulb above my head lit up - the function used (_loadAvgLinux()) did not take any account of the number of cpus in the system, which effectively penalises SMP boxes like this one.
Easy to fix. I have taken the easy route out, and put in a variable ($_num_cpu) to state the number of CPUs in the system. That means that it needs changing (possibly) manually, but has the upside of very little code-time, either by me or by the script during operation.
It will be on the site shortly.
