https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D275594 --- Comment #156 from Olivier Certner <olce@FreeBSD.org> --- (In reply to Nils Beyer from comment #153) > If the cache is too low I would assume that it has to access the disks mo= re often so that their busy times go up - as it was under the "old" FreeBSD= 's own ZFS... Indeed. (In reply to Nils Beyer from comment #154) Ok, that's more relevant hard data to consider, and as such actual progress. (In reply to Mark Millard from comment #155) That would be a good idea. This issue is overloaded a lot already, and I j= ust kept it open to remind me to investigate some problems discovered between FreeBSD and OpenZFS with respect to pruning. I have them listed elsewhere,= so in truth we could as well close this bug now. The 'arc_evict' thread probl= em has chances not to be related with this one, although only a close examinat= ion will tell. So yes, please create a new issue. We'll see if someone else who can investigate right away pops up, else I'll hopefully do it at some point. --=20 You are receiving this mail because: You are on the CC list for the bug.=
