Webfrontend how many logs lines are saved

Dear FB Team,

referring to the thread here (Webfrontend lagging) could you answer and
please add to the wiki how many lines of log are being stored?

Thanks in advance, Regards

P.S.: Currently testing the firmware on moving commands and had no errors so far (just moved some sequences!) great effort for the moment being. Z-axis moves as well with the micro stepping tuned to 1/4 very well!
