Hi Alex,

The actual test is 100 threads × 100,000 elements (10M lock-guarded 
next() calls)

I did tests with different config combinations ,  total work fixed at 
1,000,000 next() calls and varied only the thread count:

     config                       native x86-64   qemuriscv64 TCG  slowdown
     10 threads x 100k   1.35s                15.5s        ~11x
     100 threads x 10k   0.10s                110.5s      ~1100x


Trevor, do you have any suggestions how we can handle this situation ?

If no other options, I will disable the specific slow test .
