I have the same problem. I installed bbpress on another blog, to see if there were any problems with plugins.
I installed the same theme, which is Genesis, I installed one by one all the plugins to detect if it was because of this that the error was produced, but in the second forum all publications are instantaneous, while in the first take several minutes to appear.
I hope you find a solution, but I have noticed that I am not the only one having the same problem.
My blog is my forum with this: http://compraraccionesdebolsa.com/foro-de-bolsa/
Sorry if there are any misspelled words, but I am using Google Translate.
