Hello, I plan to submit a proposal in the GSOC this year for Ruby on Rails, so I would like to ask some questions first, reading more about the rails I have seen that some of the I/O operations are done in a single thread, I would like to know if this is really true (I could not identify in the code), the second one, if this is true, I think using multi thread in these operations would improve the performance of the framework, so would that be a good proposal?
