Can I get some more people to back me up, and tell the owner of arvixe.com that 90 concurrent users won't destroy a server..
Especially when it only lasts a few minutes
He's threatening to suspend myself (and I'm working on moving to a new host right now), because my site hit 90 users tonight (its normally 10-20, and I'm about to shut it down because I moved to a different network)
This isn't the first time hes complained about load either.. and the 90 user site, is vBulletin..
[16:39] arvixe: Hello
[16:39] arvixe: there are 36 people on your board
[16:39] arvixe: and says most users ever online was 88 today
[16:39] arvixe: this is not appropriate usage on a shared hosting account
[23:48] CrmrDvd: on mine?
[23:48] arvixe: sieged.net forums
[23:49] arvixe: I am surprised the server didn't crash
Probably somewhere in their TOS they say you are not allowed to use to much CPU time - and how much this is, is left totally up to them to decide.
In fact I think they're being pretty fair (depending on how expensive your shared hosting account is of course). You should be happy that they are informing you rather then suspending without notice!
If you are currently changing hosts, good - if to another shared host you might want to ask how many concurrent vbulletin users they can allow. A VPS, as suggested should allot a decent amount (you'll be able to use a lot more cpu resources on those in general), but it's hard to say (I'm quite sure the smallest jvds.com account wouldn't work- you will need more RAM).
Just inform your current host that you are currently changing servers and ask them to please not suspend until you're done. If they're fair guys they will keep your site up until after DNS changes take effect.
It won't destroy the server but these are called shared accounts for a reason. Your account is sharing resources with others on the same machine and if you're using more than your fair share then it's time to think about other alternatives.
A VPS will be a steping stone to this but for future growth a full dedicated server would be best if budget allows. No need to go wild on spec, a P3 1 Ghz system would probably suit you perfectly for some time.
Congrats on the popularity of your site btw

Well it could be those little nasties known as the bots. When they crawl, they bring friends sometimes. In any case, it is true that number of users online doesn't mean much. Some people log in but isn't necessarily posting or doing anything on the board. How active they are would help to determine more. But we don't know that from the information you provided.
90 concurrent users running all the time will eat up some resources. phpBB and IB have some good tweaking resources to allow the server to process boards quicker. There are lots of things as a site owner you can do to fix load times also. Limit certain resources such as avatars, sigs and graphics are big ones. We had a users site get second level slashdotted last month and his phpBB board was a monster. After a day of tweaking with him we worked it out.
