Light transport aircraft on approach was told to maintain 170 KTS. Because of SOP's flight crew began configuring aircraft for landing and slowing, but, no doubt due to following traffic, approach controller intervened and told them to increase speed or go around. Flight crew complied.

Narrative:
Inbound on the ILS runway 27 ATC requested an airspeed of 170 KTS. About 2 mi from the OM, we started to slow to our approach speed. ATC requested an immediate speed increase to 190 KTS or discontinue the approach. We cleaned up the aircraft and continued the approach and landed normally. ATC was unaware of our slowing (normal operations, configure prior to the marker). With the radio congestion, high traffic workload, we fell back on to procedures we are used to, not maintaining his speed request was to the marker.

Title: LTT ACFT ON APCH WAS TOLD TO MAINTAIN 170 KTS. BECAUSE OF SOP'S FLC BEGAN CONFIGURING ACFT FOR LNDG AND SLOWING, BUT, NO DOUBT DUE TO FOLLOWING TFC, APCH CTLR INTERVENED AND TOLD THEM TO INCREASE SPD OR GAR. FLC COMPLIED.
