The Kofax imports from a client machine are very slow, but the application server shows no processes or files being blocked, and no apparent issues related to CPU or memory consumption. The antivirus has been disabled on the server and the issue still persists.
The most likely reason for slowness affecting Kofax imports on a client machine is that the local antivirus (such as Cylance, Crowdstrike, etc.) is preventing perl.exe from running. It is recommended that the temp folder is also excluded from antivirus scanning to reduce the likelihood of it causing slowness associated with imports.
