Hi, Will be better if you shared your code. However, I see that you used persistence. So here are some reasons why you can see these drops:
1)You data region is less than full loaded data size stored on disk. In case if read operation can't find the value in RAM then it will read it from the disk. In the case of RANDOM_2_LRU it means that this value will be stored in RAM and some other value will be evicted from the memory. So when you will try to read this value you could see some performance drop. 2)Another problem could be related to initial loading of the values to memory from the disk. I think that before starting of the benchmark you should to warm up the Ignite by reading of the stored values for some time. Could you please check can these moments be applicable to you?
