We have studied the effect of thermal treatment on amorphous glass-coated Fe_{40}Si_{7.5}B_{15} microwires. This microwire is characterized by transverse domain wall regime only, with maximum domain wall velocity of about 1500 m/s. Annealing at 200°C slightly increases its transverse domain wall velocity, probably due to the reduction of mechanical stresses during the thermal annealing. Annealing at 300°C leads to drastical increase of domain wall mobility and domain wall velocity of the transverse domain wall up to 2500 m/s. Moreover, vortex regime appears in this case. Thanks to it, maximum domain wall velocity of around 5000 m/s was observed.
