large lag spikes/slow updates forums?

well this is hard to explain but...
for example it's 4:40 am atm and if I were to go to my own profile it'd still say my last visit to the site is well... yesterday 10 PM

it pretty much has been like this for the past half an hour.

also I recieve pm's from people who havnt been online since over 24 hours XD so I know they are online atm but yeah... their profile hassnt updated...

also, I seem to recieving PM's but I seem to get the e-mail notification from it but when I go look, there's nothing there untill a few hours later.
so I'm basicly replying though the messages I get through email >.>

not quite the best option

I'm not certain whether other people have the same issue but... would this be due to the massive amounts of pm's that are being sent?

 

Pretty much the same for me,its really irritating me! >:L
