One of my weird OCD concerns is that some of the scripts I host place a heavy load on the server. I want to make sure that, in busy times, they don’t weigh down things further. Here’s a neat little bit of PHP I wrote to simply have PHP abort the page load if the 1-minute load average is over 2.00:<\/p>\n
\n\/\/ Check the uptime first\n$fh = fopen('\/proc\/loadavg', 'r');\n$uptime = fread($fh, '4');\nfclose($fh);\n\nif ($uptime>2) {\ndie(\"Sorry, we're too busy.\");\n}\n<\/pre><\/blockquote>\nRather than die()<\/tt>, you might throw a redirect to a cache or something else. And I should point out that, of course, running this code does take some CPU time… And that this script doesn’t always make sense: you’re basically forcing a failure before the server itself forces the failure. The time it makes sense is in the way I’m using it — when some unimportant, tangential project requires inordinate resources and you want to make sure it doesn’t slow the server down too excessively, at the expense of the more important projects (e.g., the blogs).<\/p>","protected":false},"excerpt":{"rendered":"
