VB3 vs VB4 performance

[DFC005]

Should I assume that VB4 will be less server intensive than VB3 due to it being newer and most likely using smarter and leaner coding?

We currently use VB3 and have a large user base which can sometimes bring our server to the brink of it's stability. I was wondering if upgrading to VB4 would extend the server's life somewhat before we have to consider upgrading to a new server.

Cheers!

Don't assume it.

Expect your server load to go up by around 50%. That's my experiance.

the bold part will turn to this for vB 4 (for you):

most of the time, will bring our server to the brink of it's stability.
sometimes, will blow out the server completely

Upgrade your server before going for vB4. Double the RAM, get better processors and a fast drive.

From personal expirence, vBulletin 4 vs vBulletin 3's php/mysql time is about the same. Though since vBulletin 4 is serving more content (more css, more javascript, and in some cases more small images) it can put more stress on a undertuned server. There is lots you can do to decrease the load of your php app server like putting images/javascript into a CDN, or even another offsite cheap webhost.

It should not have to come to that, but since it has, it would be great if there was a tutorial made on how to best do the CDN thing you said.

Here's some handy links for that:

First thing to do though would be to run something like YSlow or WebPage test and work on the items with poor scores.

Probably worthwhile making sure you have got everything you can out of your existing server first (ie fine tune).

vb4 is based on vb3 code

vb4 is based on vb3 code

however vb4 IS slower to load

vBulletin 4 will require a more powerful server, pound-for-pound, than vBulletin 3.

So what exactly is the apparent reasoning for this? From what I have heard, VB4's code isn't that much different from VB3.8.x. Are there specific areas that VB4 is slower on the same server that would run a VB3.8 forum?

First step you can do is to optimize your PNG images.
VB4 PNG images are currently not optimized.
I have optimized them and attached it to this issue: http://www.vbulletin.com/forum/proje...?issueid=37648

Another thing you can do it to get rid of the rounded corners, this will speed up your vb4 extermely.
Add this code to the bottom of your additional.css

* { -moz-box-shadow: none !important; }
* { -webkit-box-shadow: none !important; }

* { -moz-border-radius: 0px !important; }
* { -webkit-border-radius: 0px !important; }

Thanks for the info, I'll take a look at the link.

However, the way the guys above are talking there is more than images and corners that affect VB4's performance compared to VB3. It is those things that I am interested in as I am considering moving to VB4 but am on a shared server. If I suddenly caused a 50% increase in resource usage I would be kicked off quick smart....
