>A few GC parameter tweaks brought our latency below 20ms and the application no longer drops calls.

Tick to trade latency for a modern software HFT stack needs to be under 10 _microseconds_, which is over three orders of magnitude more stringent.

10ms is target at which percentile for HFT? From what I could tell in my limited experience, GC impact is worse at the tail of latency distribution

10ms is milliseconds though not micro, that's 10us

Sorry I meant us - but at what percentile

They already just said they need 10 microseconds. 10 milliseconds is far far too slow.

1000x slow so its unacceptable .
