avoid timeout in Swiftmailer

Question

Using swiftmailer and throttler to send emails, the problem is that the browser timeouts because the throttler pauses to keep sending within limits (5 emails per minute), I think the script keeps running, is that a problem? there is a way to avoid timeout ?

// Use AntiFlood to re-connect after 100 emails
$mailer->registerPlugin(new Swift_Plugins_AntiFloodPlugin(50));

// And specify a time in seconds to pause for (30 secs)
$mailer->registerPlugin(new Swift_Plugins_AntiFloodPlugin(50, 30));



// Rate limit to 100 emails per-minute
$mailer->registerPlugin(new Swift_Plugins_ThrottlerPlugin(
  5, Swift_Plugins_ThrottlerPlugin::MESSAGES_PER_MINUTE
));

// Rate limit to 10MB per-minute
$mailer->registerPlugin(new Swift_Plugins_ThrottlerPlugin(
  1024 * 1024 * 10, Swift_Plugins_ThrottlerPlugin::BYTES_PER_MINUTE
