Differences in Performance Test Results

[darionyaphet]

I did a simple test to test the data reading performance, but the results were not as good as advertised. Is my testing method incorrect? What configuration items were missed?

        try (ChronicleMap<Integer, NewsDetail> map = ChronicleMap
                .of(Integer.class, NewsDetail.class)
                .name("example")
                .averageValue(detail)
                .entries(1000000L)
                .create()) {

            for (int i = 0; i < 10000; i++) {
                map.put(i, detail);
            }

            for (int i = 0; i < 10000; i++) {
                map.getUsing(i, detail);
            }

            long start = System.currentTimeMillis();
            for (int i = 0; i < 2000; i++) {
                map.getUsing(i, detail);
            }
            System.out.println("duration: " + (System.currentTimeMillis() - start) + "ms");
        }

duration: 171 ms

hi @darionyaphet you should use stackoverflow for questions. I would review the benchmark code in Chronicle Map and read some articles about how to benchmark software. You can of course also engage for professional help, see https://chronicle.software/support/
