Yes, I know this sounds strange, but if one have 1T filesystem full of

We have a patch that significantly speeds things up.
In the similar case 28+ years estimated for pass 0 turned into 208 hours
total
As I said before, 208 hours is unacceptable and Vitaly needs to do more
work on it. If Vitaly doesn't know how to fix it, then I need to review
his algorithms in detail.
As I wrote you the objectid handling is not the problem anymore, and I
described also that the performance problem for now is nlink calculation
on semantic rebuild pass which needs many writes on disk what is not easy
to optimize in the case with shared objectids.
by shared objectids you mean when more than one file is discovered by
fsck to have the same oid? what is the problem?
Although it could be solved
with another pass which would solve all such shared objectid problems just
before semantic rebuild pass.
