Reduce CPU usage?

Does this still work? I tried setting it to 5 minutes, and CPU is still hitting 87%. I’m getting emailed warning from the server every few minutes.

add_filter( 'wpoptimize_preload_delay', function( $original_delay ) {
    return 300000000; // Delay in microseconds, 1000000 = 1s
} );

There are several parameters you can play with:
– Using;

add_filter(‘wpoptimize_preload_delay’, ‘my_preload_delay_method’),

you can override the delay between two pages, which is currently set at 500000 (1/2 a second).

– Using;

add_filter(‘wpo_page_cache_preload_memory_threshold’, 10485760);

This filter lets you change how much memory should be left before interrupting the preload queue (10MB by default).

– Using;

add_filter(‘wpo_page_cache_preload_continue_interval’, 600);

This filter enables to change the time before the preload resumes when interrupted (600s by Default).

Is that the complete code? I get the following error when I try what you wrote:

Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, no array or string given

@aaron843 You can’t supply a numeric value to add_filter call. It should be

add_filter('wpo_page_cache_preload_continue_interval', function($interval) {
  return 1200;
});

add_filter('wpo_page_cache_preload_memory_threshold', function($threshold) {
  $new_threshold = 1234; // you desired number
  return $new_threshold;
});

Thanks I’ve tried a delay of 5 minutes. It seems there are still 5 or 6 processes that launch immediately. So I don’t know if it’s using the settings.

I set both wpo_page_cache_preload_continue_interval and wpoptimize_preload_delay to 300000000. This resulted in the creation of about 1.6 new cache files per minute over a period of 45 minutes. Server CPU loads are around 35%-70%. But I’m still getting warning emails that the CPU is hitting as much as 90% usage (normally it’s under 10% but hard to verify if this is all from cache building.)

I’ll continue to experiment to see what these values result in.
