I have published in different journals of materials science area from Elsevier, Springer and IOP. In general, the peer-review processes have taken from 6 up to 12 weeks (in the worst of cases). Is this time range reasonable for a peer-review process considering a subscription model publishing?. Are these characteristic times associated with this publishing model or it is similar to the case of open access?
How much time is reasonable for carrying out this process? In particular, I think this process could be much more efficient and fast. Is the review speed directly associated with the lack of monetary incentive for reviewers? Share your opinion!
