Hi,
I switched to Linode (512) a couple of days ago from shared hosting (HostMonster).
After 3 days of work I managed to perfectly install a Wordpress site running on CentOS 6, Nginx, PHP-FPM, MySQL. I decided to test the speeds and compare the same identical sites: one running on Linode servers and the other on HostMonster servers.
Note: this website gets a
"Grade A" on Yslow and
"Overall performance score 96". I don't use any caching plugins (W3TC, WPSC, DB Cache) for Wordpress. I know I can make it load faster if I do. And if I run the website through Cloudflare. I'm not looking for
that kind of replies to this thread...
I did some tests with Apache bench (4 x 200). The results are:
4.5 – 4.9 requests per second
~800 ms time per request
and takes around 40 seconds to complete
And for the shared hosting:
2-3 requests per second
~1400 ms time per request
and it takes around 90 seconds to complete
"It's great" you'd say, "it's around twice as fast". But real testing shows different results (using
http://whichloadsfaster.com):
Over 50 runs an improvement of only
15% (
1426ms average HostMonster |
1227ms average Linode)
And it's not only these tools. I also feel that they load the same!
Is that normal? From what I read over the Internet about nginx and PHP-FPM
I expected much better results.
There is also the cost: I pay
3.3 times more ($6 over $20), get bandwidth cap, endless headaches (SSH noob) for trying to setup a server myself, for only ~15% improvement? I switched hoping my websites would load faster! Am I doing something wrong here?
So, I am asking you to help me!
I do want to like Linode! I do presume it's not their fault! But if things stay the same I don't see me staying here...
Are there any nginx tricks you could recommend me to make this setup somehow faster? Should I mess with the HTTPD.conf at all? What else?
Thanks for your time!
P.S. I am attaching below (irrelevant code is missing, for the sake of length) the nginx.conf file, single website conf file and my httpd.conf (both improved from what I read over the Internet). In the php.ini I didn't change anything except allow for larger files to be uploaded via PHP (20MB):
