Vbulletin /server Optimization
Hello,
I need server optimization
I’m currently using vbulletin 3.8.4 version (latest stable versione). The site is on a dedicated (hostgator.com , Intel Xeon 3210 Quad Core, 4 GB RAM, PHP Version 5.2.6) with some other minor websites.
The board has about 8,000 uniques/day, and sometimes goes slow.
The CPU usage in some hours go up from 1/2 to 40/50
Plugin installed:
15+ Posts to create links, Add Banner 1.7, BB Code Manager 1.32, Catagory Icons 1.0.1, Facebook Connect 2.0.5, Gameroom 1.1.1, , Geek Auto-Link 4.8, ibProArcade for vBulletin 2.6.8, Inactive User Reminder Emails 1.0.9, Latest Threads IN Marquee, Mobile Device Force Style 2.1.3b, Mobile Style Options 0.0.10a, Plus Mood 1.0.2 , Post Thank You Hack 7.7, Radio and TV 2.0, vB Ad Management 3.14, vBadvanced Links Directory 2.0.1, vBSEO 3.3.0, vBSEO :: Conditional Signatures 1.4.1 , vBSEO :: Sitemap Generator 2.2, vBulletin Blog 1.0.5 , Welcome Headers
