At 1.4 months old UNB is steadily chugging away at blocks, and most importantly, it keeps on doing this without changes. If you want to say we're slow "aka UNB's slower than Bitcoin", that's fine for the present moment. I admit confirmations are indeed slower than we prefer, however making claims that UNB is broken is far from the truth. In fact UNB has never stopped once.
"1.4 months old" -- I presume you meant years. The Genesis block was created Wednesday, March 19, 2014 07:00:15 GMT making it roughly 16 months old. It's official description is as a 300 second coin. It may have actually been similar to that prior to the early 2015 P&D, but it's been a far cry from that ever since. UNB difficulty has been 24,965,256.2512 since before March 25, 2015.
You're apparently counting on the largesse of owners of modern ASIC mining gear to donate their resources for the welfare of UNB (my electricity costs 14.5 to 17cts/KWH so presumably you're finding a few who pay nothing or next to), but the
crypto-fact is miners generally mine for the purpose of generating funds (covering the electric bill is usually the bare minimum). UNB is a long, long way from accomplishing that. The
crypto-fact is there's no reason to expect a miner to mine UNB until the difficulty makes it at least affordable to do so. Which means that there can be no expectation of UNB transaction time becoming reasonable for a long, long time. And when that happens, don't expect it to last for longer than perhaps two to four weeks, we'll then be most likely right back to where we are now.
My last UNB coin transfer started 8PM Wednesday and the necessary sixth confirmation was aprox 10AM Friday. Can you imagine how many retail businesses would be willing to accommodate a transaction delay of even a quarter of that? How many times do you think the difficulty will have to halve before UNB transaction time becomes acceptable for real-world usage?
