We upgraded one customer to 7.5 SP1 HF3 with 3k PC and customer have lot of calls about performance after upgrade. We found out that hashing is triggering for example after computer startup (can be changed by policy) and took lot of CPU - about 50 % (Intel E8400) and HDD - about 80 MB/s. Customer have some big packages (one package have 10GB, 8000 files) which they are checking every day by policy to have latest sources on PC. In 7.1 it was ok but with 7.5 and hashing we can see lot of performance impact. I have told that any other Symantec's customer did not complain about hashing and performce but based on Resource monitor I can see such behaviour and don't believe that any other customer doesn't have the performance problem. Because of that we have to turn on LAC and other customers are on hold with upgrade to 7.5 SP1.
Is here anybody having similar problem with hashing and performance impact to system?
Btw: During this we found that registry key Delay at System Boot (secs) is not working on 7.5 SP1 HF3.
