Staking with new wallet works nice, but i have to wait sometimes several hours even with large blocks. Any idea ?
Based on what is stated below taken from HYPER's code, it's all depends on how old your coins, how many coins you have related to the current network weight. In short, you can do actually nothing, because you compete along with the others, your best choice is to increase your number of coins. But don't worry, you will still get your 5% per month.
int nStakeMinConfirmations = 20;
unsigned int nStakeMinAge = 8 * 60 * 60; // 8 hours
unsigned int nModifierInterval = 10 * 60; // time to elapse before new modifier is computed
