The server that I am on has these characteristics:
- Intel(R) Xeon(R) CPU E5506 @ 2.13GHz/24GB ddr3
- CloudLinux Server release 5.7 64 bit/litespeed webserver
- And overall are 800 clients (in whois.domaintools.com that I am looking right now the Shared IP Address of the server that I am is the "Reverse IP: 1,195 websites use this address.")
And the limits are 1gb of memory and 25 concurrent connections
In the reseller account that I have I created two accounts:
WordPress Multisite with 3 sites in under contraction/coming soon message with 2 gb ram and 30 concurrent connections (I don't know why, I am waiting for an answer from my host provider). The last 7 days from Resource Usage Details
A WordPress eZine blog with 4000-6000 monthly unique visitors/150-200 a day visits with 2 gb ram and 20 concurrent connections (I don't know why, I am waiting for an anwser from my host provider). The last 7 days from Resource Usage Details
The eZine blog has 25 Active Plugins:
- Admin Locale
- All in One SEO Pack - Pro Version
- Calendar Posts
- Contact Form 7
- Easy Mashable Social Bar
- FeedBurner FeedSmith
- Google Analytics for WordPress
- Google XML Sitemaps
- JW Player Plugin for WordPress
- NextGEN Gallery
- Really Simple CAPTCHA
- TentBlogger SEO Categories
- Top 10
- Twitter Embed
- W3 Total Cache
- WP Smush.it
- WP Smush.it NextGEN Gallery Integration
My problem is when am going to apply or save the setting of a plug in or when am going to publish or save as a draft a post I get same message:
503 Service Unavailable
The server is temporarily busy, try again later! Powered By LiteSpeed Web Server LiteSpeed Technologies is not responsible for administration and contents of this web site!
Also it takes a lot of time for my site load. It doesn't load the virtual editor of the post. And the only thing that my hosting provider suggests to optimize my site(But, I already use plug ins (CloudFlare,W3 Total Cache, WP Smush.it & WP Smush.it NextGEN Gallery Integrationor) in order to optimize my site) to move to a Cloud server.
What do you think about that? Should I move to a Cloud server or use CDN to my current reseller account or in a new host provider?
Also, does the problem really starts from me or my hosting has done a lot of overselling? Please suggest me anything that will be useful for my problem and if it's necessary to give you some information(That I might have forgot to mention) to help you understand.
