chrony maintainer here. If the initial sync is slow, it probably means the initial offset of the clock is large and chronyd is correcting it by slewing, which may take a long time. You can use the initstepslew or makestep directive to step the clock on start. A configuration optimized for a fast and tight sync with a local NTP server could be:

  server ntp.lan minpoll 2 maxpoll 4 iburst
  makestep 0.1 1
