RN516 & 6.4.2 update, initial report

After the 6.4.2 update I performed yesterday, I can confirm that performance has improved a bit. I had AV disabled after the 6.4.0 fiasco and haven't enabled it since, since performance is remarkably better without it. Did a disk balance and it completed in about 20 min. Share access is fast as it was in 6.4.1, and throughput is over 100MB/s over Gigabit Ethernet. I have the 516 with a XOR bonded link connected to a Cisco Gigabit Switch with port configured as a static LAG. From my MacBook Air w/Thunderbolt to Gigabit Ethernet adapter I'm getting over 135MB/s writes and reads. Funny thing, personal shares weren't available after the update, no-one was able to access them. After a reboot everything got back to normal. I'll report further issues should they come up.
