Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

I run my application with batch.mac file with the following content:
/control/verbose 2 /control/saveHistory /run/verbose 2 /run/beamOn 1000000
At the end of execution the time of computation is shown:
Run Summary Number of events processed : 1000000 User=289.45s Real=297.61s Sys=0.4s
Adding /vis/disable didn't influence the result.
By the way, I remembered one more question that I want to ask. When I execute the app on Windows I have:
Run Summary Number of events processed : 1000000 User=239.969s Real=0s Sys=0.031s
Here I always have Real=0s, and when I execute on Linux, I have both User and Real timings non-zeros. Can you clarify, what is the meaning of these values?
