Give an individual cron task for each Feeds import
You can indeed use Elysia and define a cron job for each of the feed imports like this:

/*
 * Feed import managed by Elysia
 */
function MYMODULE_cronapi($op, $job = NULL) {
  $items['fetch_MYFEED_cron'] = array(
    'description' =&gt; 'Fetch MYFEED',
    'rule' =&gt; '*/10 * * * *', // Every 10 minutes
    'callback' =&gt; 'MYMODULE_fetch_MYFEED_cron',
    'arguments' =&gt; array(array('MYFEED')),
  );
  return $items;
}
function MYMODULE_fetch_MYFEED_cron($feednames){
  if (function_exists('feeds_source')){
    foreach($feednames as $feedname){
      $source = feeds_source($feedname);
      $source-&gt;import();
    }
  }
}
