Feedbaaaack!! Yes, I can happily browse the site without any problems, its loading properly. I also see "digitalpoint" back and posting, so maybe he made some changes What changes were made that is making the site healthy again Oh and Thanks
The site is definitely fast except I did encounter a database error about couple of hours back and I could not access DP for more than half an hour at a stretch! The browser showed page loading 'done' but the page was completely blank! Did anybody else experience it? Regards, RightMan
Was intentional. I took the web servers offline while I was doing some database tuning to speed things up.
Wow...sounds good, particularly since it made me think the problems were yet to be resolved! Hopefully, the problems of the past will remain... in the past. Regards, RightMan
Also take note that we don't need to click the "Remember" box. This is a really good DP improvement. Congratz Also the server specs is unbelievable. Great stuff.
I have seen Shawn online for the first time I am more than 2 years old here and thanks Mr DP for bringing it back with required changes
I myself have not been posting with such fun for a long long time. The speed is awesome and the forums responses are simply heavenly!
In case people are wondering what's been going on lately... here's some speed tuning stuff that's already been done... Member List page gone (notoriously bad SQL query [unfortunately can't be any better] wrecks vBulletin database servers as the userbase grows Fixed a query I did a long time ago (opps) that is triggered when a thread is moved, created, deleted, merged, etc. - it wasn't slow at the time, but as the database has grown, it's now a better (scalable) query Deflecting nasty bots at the server-level (this is a never ending process, but I got found [and blocked] some particularly crappy ones recently) Added a few custom indexes to some vBulletin tables Did some ulimit tuning on server hardware I'm almost happy with the speed of things now... but there's a few additional tweaks/tuning I'm still working on and/or planning.
Have you thought of using something like Nginx? It can serve 10,000 connections per second (by some benchmarks I've read about). Sites like Flickr use this. You could serve your images from another hostname on a seperate server with a domain like examplestatic.com and maby use 2 or 3 subdomains to parallel the downloading of the images in the user's browse. using also a seperate hostname for images prevents the user sending useless cookies along with the http headers in the image which the server has no use for, its just a waste bandwidth. You could modify your css and turn all your common forum icons into a CSS Sprite like this. Which reduces http requests. There is many areas that you can improve upon for performance. you can read this guide. http://developer.yahoo.com/performance/rules.html
the speed is great, everything opens up real quick just one thing i have been noticing for some time, when i read a new message, it keeps staying un-read for sometime [Private Messages: Unread 1] however, after browsing for a few minutes it slowly turns to unread 0.
You mean to say you want him to upload the whole images folder to somewhere else and then edit EACH template file and change the images targets? If i were him, i would just ignore ur idea The images are being loaded either way so not a very big issue.
This was the problem of the past when we had database problems...not anymore. At least I have not observed it myself in last couple of days! Regards, RightMan
Static file serving (such as images) was never the bottleneck, the load on the database servers were. As far as PM notices not disappearing right away, what browser are you using? That might be an issue with your browser not actually retrieving the page, and just using it's cache when you go back to the home page or something. The only thing on this end that would cause it would be the slave DB servers lagging behind the master for it's replication. But at the moment, the slaves are replicating everything from the master with a lag of less than 1/1000 of a second. I'll keep my eye on it though. One thing I'm putting in place is long term monitoring of certain variables on each server (slave DB server lag behind master) so it can just be plotted over time with MRTG or something else along those lines.
maybe, i did not got any messages today so don't know if its fixed or not... am using firefox, maybe its just the cache, not a big problem since it turns to unread in a few minutes anyway...
