You may wish to try leaving your phone asleep for much longer for your tests, as I have the same issues.

Pretty much every app and feature runs pretty fast (some faster than what they did originally on my stock Gingerbread, which is great) But the incoming calls and as mentioned by blutor the phone itself is a little slow to wake.

Over the past week or so, I have tried a number of the different governor and I/O settings.

I thought "performance" with "rom" were the best settings, making it about 5 rings on average for the phone to wake on an incoming call from doze/about 3 hours. BUT I discovered that if I leave my phone for too long in doze, then it reverts back to 11 or more rings and sometimes doesn't even wake up at all, just as PARESH AHAR has mentioned.

I have tried all the other little tips such as turning off all "look up" settings, turning off "connected line ID", turning off battery optimisation on all things related to the phone, calls and texts, turning off animations, constantly keeping the phone app within my recent apps list, tried out different governors and I/Os and set my min and max freq both to 1.4GHz. You name it, I have likely tried it. I even turned off my lock screen to see if that helped at all with wakeup speed. But no, nothing has worked.

From a deep sleep of several hours, it is straight back to 11+ rings or not waking up at all.

The only thing I have found so far, is that if I manually wake up my phone ever hour or so, this seems to make the incoming calls about 5 rings for wakeup. Whether this is actually helping or if it is just a coincidence, who knows. But 5 rings is still pretty slow for an incoming call, plus if it is helping, it means trying to remember to manually wake up my phone every so often.

ALSO, I have discovered a similar issue with texts and notifications, especially calendar notifications. Texts either come through twice or sometimes not at all (a number of people told me they have text me, but I never received their texts, they thought I was ignoring them because I had not replied) and if the text's do manage to get through, when the phone is in deep sleep the phone does not wake/does not make any vibrate or message tone to say there is a text and no notification light or showing in the task bar. It is only when I happen to manually go into my text message inbox that I see there is an unread/new message which I was completely unaware of.

And the calendar notifications will not wake up the phone from a deep sleep either, so even though I have notifications set for things like birthdays, the notifications sometimes do not show up on my phone at all. Nothing in the task bar, no notification sounds or lights, nothing. So notifications are pretty much non-existent.

I think the problem, as previously mentioned, is because of the way cm13 and cm14 have been made/developed. Everything runs and it processed by the SD card instead of the phones RAM, which makes it slower at processing tasks such as calls, texts and notifications.

If items such as calls, texts, calendar and any other priority items/things which need to wake the phone immediately, were still processed via the RAM, instead of the SD card, I think this may solve the issues. If this is the case, then I think no one other than the developer will be able to resolve the issues.
