Very simple - please do not make Bitcoin transfers. Bitcoins transfers will be faster, if users will not use Bitcoins. Network lags in this way will be resolved. Please use Bitcoin only in very rare cases - may be once a year.
That's how Lightning Network works, no? (to some extend) You do not do the "real" transfer but you exchange the invoice which is "paid" one day, when the channel is closed.
Like people in bar order drinks, bartender makes the list and at the end of party each one pays his part.
