I researched this issue. GK uses memory to store data. The memory card is only used for the first fuzzy search and all. Further, it is not used at all. This decision can not be called successful. Yes, it allows you to quickly search for, but at what cost! Memory consumption is not limited in nature. As a result, the GK flies, the game. It depends on what will beat the system running out of memory. Here is an example: 1. Launch Minion Rush. 2. Launch GK. 3. I am fuzzy search. It found 40 million values. But they are in the buffer to disk. There is no problem. Memory consumption demon GK - 1,3 MB. 4. Now again looking for fuzzy search. I opt for not changed. GK starts looking devouring memory buffers: 125 MB, 188 MB, 215 MB, 237 MB, 259 MB, 278 MB, 298 MB, 316 MB, 348 MB, 387 MB ... Oh, what is it? GK was closed, and the game is closed. In my opinion, not worth the high speed flight games or utilities for hacking. Imagine that you have achieved some special situations in the game to hack it, and spent time and resources to do so. And then the game went and took off. All for nothing. Maybe all the same, it is better to look for more slowly, but with guarantees that the flight would not be? By the way, I still have this 1 GB of memory on board. What would happen if 512 or 256 MB? All will fly much earlier. And now we repeat the situation of GG: 1. Launch Minion Rush. 2. Run GG. 3. I am fuzzy search. It found 14.6 million values (the value is 0 or -1 are ignored, therefore 40 million in GK). Memory consumption demon GG - 774 KB. 4. Now again looking for fuzzy search. I opt for not changed. GG starts looking, memory consumption remains almost unchanged: 774 - 776 - 784 KB. Of course nothing is taken off, since there are no reasons for this. For fun, we spend the same with GH: 1. Launch GH. 2. I am fuzzy search. It found 39.5 million values. Memory consumption demon GH - 1.28 MB. 3. Now again looking for fuzzy search. I opt for not changed. GH begins to look, devouring memory: 259 MB - 338 MB - 384 MB ... Demon GH crashes interface GH is infinite Status. What's funny, the system even with gains GK. Well, at least the game is not relegated lucky today. Absolutely the same situation as with the GK. Conclusion: GG looking for with minimal memory consumption, but slower than the GK or GH, since it uses a memory card. But it ensures that no game, nor an attacker does not fly at the wrong time. What is more important for you, speed or reliability? Decide for yourself.
