RN314: does antivirus still slow down SMB directory listing on ReadyNAS OS 6.9.0?
I recall I saw few post months (or years?) back about how disabling Anti-Virus service on older ReadyNAS OS 6.4 (or so) helped in fixing slowness on SMB directory listing (both in ReadyNAS 300 and 100 series...), is this issue still a problem as of today?
I ask because today I enabled one RN314 (four 1TB disks in RAID6) to be used as SMB target to store not only cold backups but also to store hot data for users accessing it directly (Backups are managed through a single host which is a Server, never noticed slowness in backup deployment from Server to NAS nor from NAS to its external USB 3 disk).
SMB access permissions are fine (NAS is joined on AD) but suddenly today AD users complained about slowness in simply doing directories listing on the published SMB share (this SMB share contains 14 main folders, each one containing a lot of document files and few folders too...nothing fancy...just about a grand total of about 20GB moved into the NAS overnight, Snapshots set to hourly...few files changes really over the day, most of content is just static enough).
Know what? accessing that SMB from any host (Server included) caused total slowness...at a point users had bad time in trying to see files or folders (Microsoft Explorer green bar loads very slowly...as it was - every time - trying to index or to simply re-read folders' (and sub-folders') content.
I remembered about Anti-Virus from past threads...so I promptly disabled embedded Anti-Virus services and that action did the trick...few seconds after the same SMB directory listing was super fast...very strange for a lightly used (during the day - backup jobs take place overnight from Server to NAS or from NAS to USB disk) ReadyNAS 314...any idea if Anti-Virus service is still problematic in particular conditions (never noticed before on Backup SMB shares...)?
