Is a store effect performance to other multistore in the same magento install?
e.g.) if A store have 40000 sku products, and B store(which in same magento install with A) have only 100 sku products, is B store become slow due to A's products number like search result?
What other thing is effected to each store?
If there is many products and each store have many language store view, is it recommend to create each separate store with different magento install?
