I have no interest in this project. However I see that we do not have the same problems at all.
I have never encountered any problems of this type when I am in a small country where we are really late compared to the broadband connection.
I had a lot of problems during the beta phase and at the beginning of the project. I lost a lot of BRO but it was not important. For me, because it's free (except electricity) and also since the time I realized that the technical team is very small. There may be only one person behind this project.
It is normal that the support is not so efficient.
In any case, I think your problem is rather related to the environment of your computer. Otherwise we would all have the same problem.
I use a very small notebook that only does this and consumes very little energy, it is a portable bought used.
I also hope that "@admin" will be sensitive to all forum comments.
