We are having issues with slowness when moving files in general. Whether they are through the SMB connection or just over the network. We have found the following, but want to get people feedback on what might have worked for you.
PAN - 157715 -
Fixed an intermittent issue where SMB file transfer operations failed due to packet drops that were caused by the Content and Threat Detection (CTD) queue filling up quickly. This fix introduces a new CLI command which, when enabled, prevents these failures:
set system setting ctd nonblocking-pattern-match-qsizecheck [enable|disable]
Additional, changing the MTU can possibly help. What has everyone done around the MTU settings when troubleshooting the above.
Thanks,
Nick
