Solaris 11.3 SRU 2.4 has some fixes that are likely of interest to you if you are reading this blog. These fixes include:
- Free memory is no longer copied during live migration and suspend/resume. If you have a lot of free memory - especially free memory that wasn't free at some point - this can significantly reduce migration time.
- During zoneadm migrate, progress reports keep you up to date on how the migration is progressing.
- vmstat and iostat are now much faster to start in zones.
- Operations involving access to device nodes in /dev/zvol are much faster. That is, ls, find, and open() may be faster. There are no zone-specific changes that would impact the performance of reads and writes to ZFS volumes.
