Abstract: Some embodiments provide a method for evaluating locations of applications in a multi-cloud network with applications located in different cloud datacenters of one or more cloud providers. The method receives data for flows collected from the cloud datacenters. The data for each flow indicates a source and destination of the flow and applications to which at least one of the source and destination of the flow belong.

Based on data from the cloud providers, the method determines a cost for each of the egress flows and a cost associated with each of the applications. The method provides these costs to users of the network for the users to optimize locations of the applications in the different cloud datacenters.

When the global recycle queue is determined to be a lowest priority global recycle queue and the buffer is determined to be a least recently used buffer, the buffer is removed from the global recycle queue and inserted into a per-thread recycle queue. When the buffer is least recently used in the per-thread recycle queue, the buffer is removed from the per-thread recycle queue and placed in a free pool. With this technology, buffer cache can be more efficiently managed, particularly with respect to aging and scavenging operations, among other advantages.
