With SSD, we find that garbage collection will become a very significant bottleneck, especially for systems which have little control over the storage layer and rely on Java memory management. Big heapsizes make the cost of garbage collection expensive, especially the single threaded CMS Initial mark. We believe that data systems must revisit their caching strategies with SSDs. In this regard, SSD has provided an efficient solution for handling fragmentation and moving towards predictable multitenancy.
