Departing IFR out of LAX. Climbing thru 5000. Crossing 5000 feet, Departure says "Maintain 280 (knots) or better, climb and maintain 17,000"

Since this is an "ATC directive", you are approved to fly 280 below 10,000, or do you wait until 10,000 before selecting 280?

I say do it when ATC says to do it, since he may be seeing soon-to-merge electronic dots on his radar scope

Thanks

• What aircraft
• What was your rate of climb
• Which SID if any?
• How far offshore ?

If you’re flying a big jet and your rate of climb at the time of transmission was 3000+ then it’s only a minute and a half to 10,000.
