?Regarding CPU load, a single thread of execution exists in the program so (at most) one core is used. So if you have 8 cores, it means that it is 8 to 16 times slower than a program able to use all the cores & CPU redundancy of the machine.
In my tests, indeed, a core looks fully utilized. To me, scanning 1M key-values per second is pretty ok, but indeed, if LMAX got 6M transactions per core per second, it can perhaps go up, but something tells me this will not be the limitation of the typical application.

I have write and run a simple performance test to check IgniteCache#localEntries and found that current method is not enough fast. Ignite ignite = Ignition.start(); CacheConfiguration<UUID, UUID> cacheConfiguration = new CacheConfiguration<>(); cacheConfiguration.setBackups(0); IgniteCache<UUID, UUID> cache = ignite.getOrCreateCache("test.cache"); for (int i = 0; i < 1_000_000; i++) { cache.put(UUID.randomUUID(), UUID.randomUUID()); } long startTime = System.currentTimeMillis(); cache.localEntries(CachePeekMode.PRIMARY).forEach(entry -> { }); System.out.println(String.format("Complete in: %dms", System.currentTimeMillis() - startTime)); Reading local entries take about 1s (1000 rows per ms) that's is low. Test was run on server with provided configuration with default Ignite configs, load average was about 0 and CPU was not busy more than 10% Intel(R) Xeon(R) CPU E5645 @ 2.40GHz May be I do or configure something wrong or current speed is normal?
