Recently a new configuration of a computer, with a better cpu - AMD Ryzen 7 8700G w/ Radeon 780M Graphics, but maple computation is particularly slow, cpu call special less computation is particularly slow, is there any way to improve?

How can I solve this function faster? solve the solution is more accurate, but the solution speed is too slow, the use of fsolve to solve the speed is faster, but the solution is not accurate, what is the solution fast and accurate?question11.mw
