If we look at the confirmations (because that's what you're obviously referring to), there is not much that one can do other than to wait for new blocks to be found (assuming you pay a proper fee and a miner picks up your transaction).

Regarding SegWit activation, SegWit will activate after 1399 blocks (which translates into roughly 10 days). In case you're wondering, even SegWit won't be doing anything in terms of improving confirmation times.
