Single Threaded Training is faster than multi threading

[ignis-sec]

Describe the bug
With markopy, -t 1 will complete the training faster than -t 10

To Reproduce
Steps to reproduce the behavior:

1. Train a base model with a corpus using -t 1
2. Train the same base model with the same corpus using -t 10
3. Compare runtime
4. Contemplate the hours i spent input scheduling for training during development
