This modifies the server to track the recently confirmed transactions using a much more efficient APBF instead of an LRU cache which has significant overhead in addition to having to store the entirety of all items added to it. This is acceptable because false positives are acceptable as the goal is to deduplicate transaction requests which is an ideal case for APBFs. More concretely, the current LRU cache that stores the recently confirmed transactions takes around 2.67 MiB per profiling while the new APBF only takes around 180 KiB, a reduction of around 93%, while exhibiting roughly the same computational performance.
