top content code:

class ControllerCommonContentTop extends Controller {
    public function index() {
        $this->load->model('design/layout');
        if (isset($this->request->get['route'])) {
            $route = (string)$this->request->get['route'];
        } else {
            $route = 'common/home';
        }
        $layout_id = 0;

        if ($route == 'product/category' && isset($this->request->get['path'])) {
            $this->load->model('catalog/category');

            $path = explode('_', (string)$this->request->get['path']);

            $layout_id = $this->model_catalog_category->getCategoryLayoutId(end($path));
        }

        if ($route == 'product/product' && isset($this->request->get['product_id'])) {
            $this->load->model('catalog/product');

            $layout_id = $this->model_catalog_product->getProductLayoutId($this->request->get['product_id']);
        }
        if ($route == 'information/information' && isset($this->request->get['information_id'])) {
            $this->load->model('catalog/information');

            $layout_id = $this->model_catalog_information->getInformationLayoutId($this->request->get['information_id']);
        }
        if (!$layout_id) {
            $layout_id = $this->model_design_layout->getLayout($route);
        }

        if (!$layout_id) {
            $layout_id = $this->config->get('config_layout_id');
        }
        $this->load->model('extension/module');

        $data['modules'] = array();

        $modules = $this->model_design_layout->getLayoutModules($layout_id, 'content_top');

        foreach ($modules as $module) {
            $part = explode('.', $module['code']);

            if (isset($part[0]) && $this->config->get($part[0] . '_status')) {
                $data['modules'][] = $this->load->controller('module/' . $part[0]);
            }

            if (isset($part[1])) {
                $setting_info = $this->model_extension_module->getModule($part[1]);

                if ($setting_info && $setting_info['status']) {
                    $data['modules'][] = $this->load->controller('module/' . $part[0], $setting_info);
                }
            }
        }
        if (file_exists(DIR_TEMPLATE . $this->config->get('config_template') . '/template/common/content_top.tpl')) {

Step back from the code and consider the entire page delivery.

Many times, performance issues can be resolved with the following:

1. Compression - http://httpd.apache.org/docs/2.2/mod/mod_deflate.html
2. Caching - https://httpd.apache.org/docs/2.4/mod/mod_expires.html
3. Proper sizing of images - Be sure the images are being sent in about the same size as they will be rendered
4. Minification - https://en.wikipedia.org/wiki/Minification_%28programming%29
5. Reduction in the number of requests made - A good example of this is sprites
6. Put JavaScript at the end of the body
