HazelNuts39,
Concerning "SPD LIM RED FLAG", note that I'm also refering to those ACARS in the sequence:
2:10:29 -.1/WRN/0210 228300 2 06 > FLAG ON CAPT PFD SPD LIMIT
2:10:41 -.1/WRN/0210 228301 2 06 > FLAG ON F/O PFD SPD LIMIT
Those two FLAGS, despite the lag in recieving time, will be displayed on the PFD (and all characteristic speeds removed) as soon AP OFF + ALT2 switch (immediately or up to 10 seconds after AP OFF).

In fact, out of 15 ACARS time stamped 0210:
- 10 are Real Time ECAM/FLAGS
- 1 is a Real Time Position Report (kicking between those two SPD LIMIT flags above)
- 2 are System Maintenance Advisory (not displayed in flight)
- 2 are the related Faults to the above sequence which are delayed by the opening of the 1 min correlation window.

Now, if all of them kicked at the exact same time (0210:05, but it is not the case), they will be queued and it will take for the SATCOM nearly the same ammount of time up to the last fault recieved at 0211:55. The difference is only a small lag of 8-10 seconds between two FLAGs that were displayed at the same time in F/O, and CAPT PFDs... hence, this small lag is due to satellite's bandwith rather than system lag.
The processing time was nearly constant at 6 seconds +/- 1 second per ACARS, consequently, only one more message could have been sent during the same time window (01'50'') without such little lag.
