I understand the amount of domains on a server eats up resources and slows it down, however I was wondering whether the amount of subdomains also affected the server in this way?

Thanks.

Every byte added on the server is adding load to it ;), What exactly is your question ?

cheers :D

his questionis... do subdomains eat up resources and slow things down?

>> i have no idea....

do subdomains eat up resources as much as just a domain does. You know, limiting domains on each server is a good idea... however when u apply say upto 50 subdomains per account... things could go wrong?

There is no difference.
You can run server intensive applications from a sub domain as easily as from the main domain.

So one offering say 100sub-domains per account is risky?

Not being an expert and reading what's here and trying to make sense of it, what I think they are saying is.

Its not the number of users so much as what you allow those users to do.

If you allow 1000 sub domains on an account makes no more difference than allowing no sub domains so long as the resources each account can use up is restricted.

The sub domains therefore use up the resources allowed in the individual account and not the server itself except where impacted by the account in general.

so a user that has no sub domains who is allowed to use 1gb of bandwidth and 100mb of webspace will use as many resources as a user with 1000 sub domains who is allowed to use 1gb of bandwidth and 100mb of space.

However, this is where the not an expert bit comes in, what do you do if a user regularly goes over the resources limit? This surely impacts on what other users of that server gets?

No more risky than offering one domain. You set limits on your plans and the client is expected to comply with these limits regardless of the number of sub domains.

It can cause file descriptor problem when there are too many virtualhosts~ More rams get used up. That's why I set limit on my subdomains and domains~ :stickout:

I think you can use rewrite_rule to setup subdomains and that would be better~ :angel:
