It is odd that it is always slow. I cannot reproduce that. For me it loads fast and sometimes it doesn’t. I can see that also when I check the processor load. Sometimes it hits 100% for some reason and for the rest it is at a few percent. I have several timers running, but it never seems to stall on the same thing. It is always something else.
Although for the last two days I am getting system messages of high memory usage by the server for a certain time. It looks like someone or something is making a lot of connections at certain time slots.
As I am unable to link it to a specific script, I am planning to set-up a reverse proxy, which should theoretically help.
