I thought with FIX I would be getting well sub second trade execution, something in the double or low triple digit milliseconds. In practice I'm seeing extremely slow execution.

For instnace I just recently put in a market order to sell ES:

20240404-14:53:54.000000000 : 8=FIX.4.49=14535=D34=249=AThaker****52=20240404-14:53:54.00056=OEC_TEST1=API01****11=99938=140=154=255=ES60=20240404-14:53:54200=202406461=FXXXXS10=094


And it did execute but took nearly a full minute:

Is FIX usually this slow? Is this just an artifact of using the Stage Environment connection? This seems unusably slow.

Thank you for bringing this to our attention. No, it should not be so slow. This may be due to a recent issue whose fix will go out this weekend.
Please let us know if you have further issues after that time.
