Tic toc vs profiler for Arduino

Hello everyone,
I am trying to optimize a quadratic program solver for use in realtime on an Arduino for a control process. I have programmed two solvers, let's call them Solver 1 and Solver 2. When I use tic toc, there is almost no difference in computation time, but when I use the profiler, Solver 2 is almost 20 times faster than Solver 1. I read somewhere that the profiler only uses a single thread, while tic toc tends more to real time performance.
My question is: would I notice this significant performance increase when using Solver 2 on an Arduino, or would performance be similar using Solver 1? I am not that familier with an Arduino, and am also unable to test code on an Arduino unfortunately, but I could imagine that an Arduino could only use a single thread. Any insight would be greatly appreciated.
Martijn

If reducing to one thread does not change much then probably they will be close on the arduino.

You can get an idea by changing the number of threads to 1
Profile is not a good estimation of real time, as profiling disables optimization by the execution engine.
