  PSR J0537$-$6910 is the most active glitching pulsar with a glitch rate
$\sim0.3$ yr $^{-1}$. We have reanalysed 45 glitches of PSR J0537$-$6910
published in the literature and have done post-glitch timing fits within the
vortex creep model. Moment of inertia fractions of the superfluid regions
participating in glitches are obtained for each event and the model predictions
for the inter-glitch time are confronted with the observed time-scales.
Similarities and differences with the glitching behaviours of the well studied
Crab and Vela pulsars are highlighted. From superfluid recoupling time-scales
we estimate an inner crust temperature of $T=0.9\times10^{8}$ K for PSR
J0537$-$6910. It is found that PSR J0537$-$6910 glitches leave behind
persistent shifts similar to those observed from the Crab pulsar. These
persistent shifts are responsible for the long term increase of the spin-down
rate of PSR J0537$-$6910 and the apparent negative trend in its braking. Glitch
magnitudes and persistent shifts of PSR J0537$-$6910 are consistent with the
scenario that this is a young pulsar in the process of developing new vortex
traps. We determine a braking index $n=2.7(4)$ after glitch induced
contributions to the rotational evolution have been removed.
