I'm investigating the feasibility of migrating from UFS to ZFS for a mail-store supporting 20K users. I need separate quotas for all of my users, which forces me to create separate ZFS file systems for each user. I had read that there were issues with slow boot times with thousands of ZFS file systems, but it seemed that a fix had been released with Solaris 10 U3.
I just recently setup OpenSolaris b66 on a T2000 Logical Domain (4 VCPU, 4GB RAM, SAS-backed virtual storage) and created 50K file systems as a test, but I've found boot times to be very slow (> 5 hours) and operations on ZFS (ex., zfs set) to also be pretty slow. Has there been a regression, or do I need to set tuning factors (ex., in /etc/system)? We're currently have ZFS deployed for a near-line backup system with tens of millions of files, and it's working great, so we'd also like to move some of our other datasets to it.
