UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
Hi,
I have a general question out of curiosity more than anything.
 I've been fortunate enough to upgrade my PC recently and enjoy quite fast integrations using APP. there is one part of the process however that does take a significant portion of the processing time where the PC does not seem to be working all that hard.
during integrate light frames, cpu usage comes in short bursts followed by a decent gap, curious as to whats the bottle neck here.
running an amd 5900x with gen4 ssd capable of 5gb/s transfers, i use all 24 threads and 50/64GB Ram allocated to APP

I'm not sure as I didn't write the algorithm, but maybe this is also due to the processes other then LNC calculations, like preparing the data and writing to disk. These things are always thought about regarding optimization so they may change a bit as well.
