Hi, I am in the process of creating a site which will be serving lots(say 15,000 ) of impressions a day of mostly plain text. I am using joomla for it. Can joomla withstand heavy loads. I will be scanning lots of pages and uploading them(converting them into greyscale or using ocr). What will be the size of a single page.(It depends on a lot but whats the usual size). Thank you.
The joomla.org site is done with "joomla" and is already taking a much heavier load than you have mentioned here.
But then its managed by some of the greatest developers. A inferior product on great hands works wonders.
Yes, this is what Joomla is designed to do. Also check out Drupal if you intend to have all of those visitors be registered users - the strength of Drupal is in hqaving thousands and thousand of users. But if they are simply unregistered visitors Joomla is great.
I'm not a programmer, I'm a designer, but I know more than one programmer in different countries that INSIST Drupal is superiour for having many users, where Joomla and Wordpress were designed to only have a handful or a dozen. I don't think, in my opinion, that they are likely any worse at handling databases than Drupal, I think it's just what they are designed to do versus what Drupal is designed to do. You'll have to ask questions yourself and look into it, but I'm just passing along what's I've heard over and over again.
I've built sites in Joomla and wordpress. and, i prefer wordpress. I haven't had any problems with the site handling the type of traffic you are refering to.
Drupal can handle both users very well. Infact many server tests have proved dupal to work faster than joomla in all sense. I have tried both joomla and drupal. Joomla attracted me with straight forward things to learn and most of all great looking templates available! But take my advice go with drupal, its not a child's toy to play with but a serious game which can save you a lot many times. Be it the server load, SEO, user managment or great community support drupal is the most superior CMS/ framework out there.
I use joomla few years form now and I use wordpress too, but not that long. I have 4 websites on my dedicated server. 3 of them are made in joomla and one in wordpress. I have a lot of visits. On joomla sites sometimes I get up to 100k unique visits per day and on Wp site I get up to 20k. I can tell you that I had a lot of problems with my WP website before i installed SUPER CACHE. Even now, that one site can cause problems. Wordpress = death fo APACHE... So I recommend you to use joomla...
Drupal would be useful.... if you are new to something .. then I suggest you to use the one THAT YOU ARE FAMILIAR..
