Forums General Discussion is 50 GB a month of bandwidth enaugh for a server?

Holding 500-1000 busy users?

Holding, 1000 users day in day out, then i'd imagine yes.

(The following calculation may very well be incorrect, but it will give you an idea).

50GB is 51200mb (50*1024)
51200 divided by 30 (average number of days, in month)
leaves you with 1706mb per day bandwidth
dividing that by 1000 users, gives each user 1.7mb bandwidth per day.
1.7mb is 1740kb which in turn is 1782579k
and 1k is 1 character, so we are saying the average person can type 1782579 characters per day, saying the average sentence is 40 characters, thats 44564 lines per day they can type before you need to worry.

Eamonn.

Plus every other command to send to and from the server.....

yeah, but suffice to say even after that there'd be plenty left:)

You're calculating incoming bandwidth, but remember that for every message that's received at least one reply is going to be sent (with the exception of a few server commands). When you take into account that on a channel of 50 people every message has to be relayed to the 49 other people in the channel your bandwidth for each message (in that channel at least) have to be increased 50x.

Also, there is the databases access that eats bandwidth, among other things. If the site has a lot of images, so the number of characters left to type (in your theory) are already falling down... but it's enough.

To take an exemple from a website that really does exist, a mIRC website with 1500-2000 unique visitors a day (few images if not of the screenshots section... but there are more than a thousand files available to download), it eats 30gb of bandwidth a month but it's growing every month, so you should be ok with 50gb for your site.

He's talking about an IRC server though. No images, databases, files, or other external sources required.

Depends on how many users are going to connected to the network, if its for a small ircd, with approx 20 - 100 people, 50gigs of bandwidth is more then enough.

If you are looking at linking to a network, you will have to work out how large the network is, and can possibly grow to, as well as what type of user base there is.

Rizon, which has a lot of large channels, bandwidth requirements are a lot higher then say, a smaller network with smaller user based channels. Large channels scrolling constant data to around 2500 - 4000 people will eat up bandwidth quickly - but it all depends if those users are on your server.

Only advice is to work out how many people you think will be on your IRCd, and take it from there, you maybe better off getting an ircd shell from a provider which limits the amount of users, which usually works out cheaper.

Good Luck!
