Peer review in Computer Science Journals I work on both in the area of pure Computer Science and in the area of Computational Chemistry/Biology.

Till now I have submitted papers to well known venues(journals) of both these fields. I don't understand the following situations after paper submission in both these fields:


Submitted papers in non-CS journals follow a quick review procedure i.e. submission - editor assignment - reviewer invited - under review - review completed - [...] Turnaround : 3 months
But, for pure CS Journals, every step is late except the first step which is obvious. Turnaround: 10-12 months


What can we infer given such situations in peer review world?

Note: I am talking about majority of journals in both these mentioned fields.
In computer science, unlike in the majority of other academic fields, most research is published as articles in conference proceedings, and conferences do follow a quick review process. I imagine that the pressure on journals to provide a quick review process is thus less strong.
