Magento memory performance

I have a huge problem in Magento 1.7.0.2 when importing ~400k of products. Due to an custom interface i created a custom product import where the products get created, upsellungs/cross-sellings get saved.

Pseudo:

do {
  if( $_product = Mage::getModel(catalog/product)->loadByAttribute('sku', $sku)){
     return $_product;
  }else{
     $product = $this->createProduct();
     $product->save();
  }
}while(!$end_of_import);

Each processed product (load/save...) needs ~180kb of memory. The problem: the memory never gets released! So after ~50k-60k of imported products the allowed memory size of 10gb is exhausted.

I tried different solutions as posted here or here but no effect.

Call $product->clearInstance() after the save, so not only the product itself is removed, but also everything else attached to it.

How about the indexes? On the backend interface the Indexing is set to "update on save" by default. If you iterate over a lot of products and save them as you described, a reindexing process will start after each save. Try to change the mode to "Manual" (System/Index management), and execute the import afterwards.

Have you tried using unset ? for $_product and $product?
