Trying to make Re# C++ to parse UE sources and failed like 10 times on two different PC. I have a feeling that it runs out of memory and VS2017 crashes, but I also can be wrong. Half of the sources (according to progress bar) is parsed fairly ok. I can see that VS2017 process writes and reads 2-3Mb/s and when it reaches 2/3 it writes like 0.1Mb/s and makes VS2017 extremely choppy. I can understand that parsing such a huge code base takes some time but why blocking VS2017 editor? You probably need to update some db in ui thread but can't you do it when you have all the data and make sure it's quick? After 30mins its impossible to type anything.
I think half a year ago it worked much better. At least I don't remember having such negative experience. Yes it was slow, but eventually it was ok. It's quite weird that VS can compile whole UE much faster than ReSharper can index (and with latest versions it can't even index it).
