Vsserv Hammering Disk
I upgraded to IS 2012 from IS 2011 yesterday. I've noticed that vsserv is hammering the internal SSD disk with reads at about 7Mbps when Auto Scan is turned on. There are about 100 vsservs threads active, reading many files. CPU usage is <10% total, with one core very high.
I had previously done a manual full system scan, but with Auto Scan ON, vsserv was still reading files that had been scanned by the full system scan.
I have changed the on-access scanning option from Normal to Custom with "scan only new and changed files" checked. This has eliminated the constant disk hammering. If this works the way I think it does, I can run a full system scan occasionally and run with Auto Scan OFF and still get virus protection.
