I do not speak English well, I use Google translator.
I play MTT in three rooms (PokerStars, 888poker, iPoker)
I have been using hm3 since November 2020. At the moment version hm3 (v22.214.171.124)
I have such a habit that every new month I create a new database. Then I import my hand history there.
Now about the problem. When creating notes for all previous months, the speed of "hands per second" was 1500-2500.
And this month the speed dropped to 25 "hands per second". This only happens with iPoker hand histories. For other hand histories (PokerStars, 888poker) speed is still high 1500-2500
