Unresponsive/Slow NAS performance post Anti-Virus + upgrade
Hello all Since upgrading to firmware V6.4.1 and upgrading Ant-virus + to version 2.0.3 I have been suffering extraordinary slow/unresponsive performance from my Ready NAS 102. For example: There have been times when it would not allow me to login to the web GUI. Windows Vista, 7 and 10 explorer progress bars took minutes to load directory structures. I noticed an improvement after rebooting the NAS but this was short lived less than 15 minutes. The 4TB NAS drives are only about 25% full operating in a home environment so has a light duty cycle. The Web GUI says the drives are healthy and are operating in the ~38 degree Celsius. The fan is running about ~800 rpm. No virus have ever been found on these drives. Ani-Virus + is the only application that I run on the NAS other than the default ones. I turned off AFS (Apple File System) as not required. I have cleaned out the dust accumulation from 2 years use but the CPU temperature remained in the mid-high 60 degree Celsius range. I felt this is a little higher than it should be. On a hunch I decided to turn off the Anti-Virus + process. A partly loaded file suddenly and dramatically completed loading and equally importantly the CPU temperature dropped to mid-50s degree Celsius within a few minutes. I then performed some file loading tests using an I5 Lenovo T430 laptop. Test file was an XLS of 1.8GB. Application was pre-loaded. Anti-Virus off 7 seconds CPU temp ~55 degrees C Anti-Virus on 3:52 CPU temp rose to ~66 degrees Celsius during the load. I do not any pre-upgrade load time figures for comparison but load times where acceptable. The conclusion is that there is something seriously wrong with the latest version of Anti-Virus + or the priority assigned to the application. I note that other users are experiencing similar response problems but the little I have read have not done much in the way of quantitative measurements. I am reluctant to turn off Anti-Virus + but see little alternative. How can I roll back the Anti-Virus + application and/or when is a fix coming? Regards DavidBa
