X1018 - very slow UI, any suggestions?

I have an X1018 managed switch, it seems to work OK but the web UI is painfully slow. I often click things a couple of times because I'm not sure if it has worked the first time. Then after 30 seconds the screen updates and it has worked but just sooo slowly. Does anybody else have this issue, is it a known thing or is there something I could do to speed things up? There maybe services running that I'm not using that could be disabled, perhaps!
