Rock solid with Post-Fix!

I did made my pergola about two years ago and used one bag of Post-Fix
(B&Q)
per upright! (Very easy to use!)

My posts are rock solid and have endured gales without movement of
flexing!

That is just what we used with the same results)

Flexing is primarily dependent on the gauge of the timer used, and has
little to do with how they are fixed into the ground. I tend to use
3x3" and 3x2", so they flex a bit. Mine have never moved, and I don't
use concrete of any sort.
