Occasionaly I have seen it be slower than normal, but not as long as you are reporting.
Does the file extension make a difference?

Try running Taskmanger, details tab, sort decending by name, select ZTW64.exe, then switch to ZTree and then press context or Shift-F10.
Is the delay launching zshell64.exe, or between zshell64.exe staring and the menu showing?

Are there lots of applications installed the hook the context menu?

You might need to run sysinternals procmon filtered for the ZTW64.exe and zshell64.exe processes, to see what is going on.


Some thoughts
The slow then fast behaviour, sound like caching getting flushed, i.e. while in the cache it fast, and when the cache gets flushed much slower.
But which cache?

Does the system have plenty of free memory?
