you can PM me the exact problems you face, exact means how and when things happen. After that i try to reproduce it which is why i need to know which apps you have running when issues occur and generally as many details as possible.I actually want the roms to be perfect so I don't mind following more steps for instructions through pm if u have some for dummies so I won't sound like a noob getting embarrassed. Don't worry I won't be a smart ass about it or offensive in any way. If this works out for someone like me who is able to fix it then it will be shared with everyone else and u will be considered a genius imo
Thing is that VERY often things are either compatibility issues and/or app/setup/user space related and not making sense at first glance.
Also at times terms are relative. Someone can see a lag and compare to his last phone and somone else can make a hardware (cpu, gpu etc.) assessment and see the so called lag as obviously normal for the hardware at play.
I've really seen people complaining about lags and stuttering while playing heavy games on devices with mediocre GPU/GPU combos and asking for solutions, so we have to make absolutely sure that the culprit is not the app(s) in use etc.
The best way to start troubleshooting would be to install the ROM naked with only root if needed and test performance. In case it's bad (problem occurs) we would start with the kernel settings, if it performs well you'd start to add your user apps in increments and observe after which increment the trouble begins, which means, it must be an app/setting changed/added in that last batch that is most probably the culprit.
To avoid multiple clean setups you'd better make nandroid backups after as small as possible steps to be able to revert to last working and go from there.
I recommend to start like this. In case you prefer to seek the needle in a heystack, means to start troubleshooting with a fully setup device, we have to see how far we get the number of possible culprits is increasing exponentially and a sophisticated setup ends with a very steep climb, means every single change opens up an endless number of new possible combos that could cause an issue.
However just send PMs and give me time to reply since i'm a busy person spending a lot of time offline while on the move.
EDIT:
I've seen your PM and replied
