Performance degradation in embed mode

[Dmitriy]

Hello Igniters,

I'm using an spring web application with the embed Ignite cache.
When we run in unit-tests, the insertion time into the cache is about 10 000
values/seconds.
But when the application is running on the Apache Tomcat server, the insert
is very slow (about 5 minutes). 
The application runs on one node.
CPU usage: 15-20%.

So do you have any idea what the problem could be?

  @PostConstruct
  public void putAllCache() {
    Map<CacheId, DataUnit> map = new HashMap<>();
    for (long l = 0; l < 10_000L; l++) {
      map.put(
        new CacheId(new Random().nextLong(), new Random().nextLong()),
        new DataUnit(new Random().nextLong(), new Random().nextLong(), new
Random().nextLong())
      );
    }


    IgniteConfiguration configuration = new IgniteConfiguration();
    String regionName = "MyRegion";
    DataRegionConfiguration dataRegionConfiguration = new
DataRegionConfiguration();
    dataRegionConfiguration.setName(regionName);
    dataRegionConfiguration.setMaxSize(DataUnits.MEGABYTE.getBytes(1024));
    dataRegionConfiguration.setPersistenceEnabled(false);
    DataStorageConfiguration dataStorageConfiguration = new
DataStorageConfiguration();
    dataStorageConfiguration.setDataRegionConfigurations(
      new DataRegionConfiguration[] {dataRegionConfiguration}
    );
    configuration.setDataStorageConfiguration(dataStorageConfiguration);

    Ignite ignite = Ignition.getOrStart(configuration);
    String cacheName = "MyCache";
    CacheConfiguration<CacheId, DataUnit> cacheConfiguration = new
CacheConfiguration();
    cacheConfiguration.setName(cacheName);
    cacheConfiguration.setIndexedTypes(CacheId.class, DataUnit.class);
    cacheConfiguration.setDataRegionName(regionName);
    cacheConfiguration.setBackups(1);
    cacheConfiguration.setCacheMode(CacheMode.PARTITIONED);
    cacheConfiguration.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);

    IgniteCache<CacheId, DataUnit> cache =
ignite.getOrCreateCache(cacheConfiguration);

    LOGGER.info("Start putAll.");
    cache.putAll(map);
    LOGGER.info("End putAll.");
  }
