I too think the problem is not with PBS 2.3-3 but with the kernel, and on my system kernel 6.1.10 runs really well. The problem I have identified with kernel 5.15.85 is incredibly slow performance on NFS storage. 3 days to finish a garbage collector on a 25 Tbyte SSD datastore (in NFS) versus 3 hours now. Yes, I think the best analysis is to upgrade to PBS 2.3-3 while keeping the system running kernel 6.1.10. I will let you know Thank you very much Luca
