Hello Guys, Welcome to Hosting Lovers!
If you are planning to buy InterServer Shared hosting, and you want to know the performance of InterServer Shared hosting, then you are in the right place. In this blog post, We will test the speed and performance of InterServer Shared hosting with 10+ different and extensive tests.
Let’s Get Started!
InterServer Shared Hosting
InterServer is providing shared hosting from 1999. InterServer offers only one plan in the shared hosting, which is called Standard Web Hosting. In this plan, you can host unlimited websites and you will get Unlimited ULTRA SSD Storage, Unlimited E-Mail Accounts, Free SSL Certificates and many more features.

Testing Environment
To test InterServer shared hosting speed and performance, I bought the Standard shared hosting plan of InterServer. If you are a regular reader of this blog, you will already know that I create the same testing website when I perform speed tests. After buying the plan, I installed WordPress and connected it with my domain which I bought from NameCheap.
I do not want to run tests on a blank website, so I installed Blocksy Theme and one of its demo websites called ‘Tasty.’ I have to install four additional extra plugins with the demo website: Blocksy Companion, WP Forms Lite, Stackable, Recipe Card Blocks by WPZOOM.
Hosting: InterServer Shared Hosting
Plan: Standard Web Hosting
Server Location: USA
WordPress Version: Latest
Themes: Blocksy (Active), Twenty twenty One
Plugins: Blocksy Companion, WP Forms Lite, Stackable, Recipe Card Blocks by WPZOOM
After setting this testing environment, I did not perform any extra optimizations like caching, Image compressing, modification, or any other kind of speed improvement. It would be best if you always did these optimizations to improve your website, but I wanted to know the actual performance of InterServer Shared hosting without any optimizations.
Quick Disclaimer:
I want to inform you guys that all the results are honest and authentic in this blog post. Also, this blog post is not sponsored by InterServer hosting or any other hosting.
To do these kinds of tests, I have to spend a lot of money from my pocket, So I would like to request that if you want to buy InterServer Shared Hosting or any other hosting, please use our affiliate links. You will get an extra discount, and this website will earn a small amount of commission from it. So, we can do more feature speed tests, reviews, and comparisons without any sponsors.
Now, without wasting your precious time, let’s start testing.
KeyCDN Test
The first test we will do is the KeyCDN Test. With the KeyCDN test, we can measure website total load time and TTFB from 10+ worldwide locations.
TTFB Test
Server Location | Test 1 | Test 2 | Test 3 |
---|---|---|---|
Frankfurt | 761 ms | 675 ms | 760 ms |
Amsterdam | 1 s | 913 ms | 930 ms |
London | 967 ms | 968 ms | 926 ms |
New York | 615 ms | 537 ms | 737 ms |
Dallas | 810 ms | 741 ms | 789 ms |
San Francisco | 697 ms | 644 ms | 636 ms |
Singapore | 1.16 s | 1.19 s | 1.94 s |
Sydney | 1.25 s | 1.34 s | 2 s |
Tokyo | 1.09 s | 1.27 s | 1.87 s |
Bangalore | 1.1 s | 1.15 s | 1.17 s |
Global Average | 945 ms | 942 ms | 1.17 s |

Frankfurt | 2.45 s |
Amsterdam | 1.97 s |
London | 2.81 s |
New York | 1.57 s |
Dallas | 3.01 s |
San Francisco | 1.88 s |
Singapore | 4.52 s |
Sydney | 4.09 s |
Tokyo | 3.37 s |
Bangalore | 4.39 s |
Global Average | 3 s |

Google PageSpeed Test
Google PageSpeed test is the essential test. Google PageSpeed tool is the official tool of Google for measuring website speed and performance. Google PageSpeed test can be different from test to test. Therefore I took three different results from three different days.

Largest Contentful Paint | 0.9 s | 0.9 s | 0.9 s |
Speed Index | 1.8 s | 1.9 s | 2.3 s |

Pingdom Test
In the Pingdom test, we can measure website fully loaded time from 7 worldwide locations.
Server Location | Load Time |
---|---|
Tokyo – Japan | 3.33 s |
Frankfurt – Germany | 2.33 s |
London – UK | 1.96 s |
Washington D.C. – USA | 1.61 s |

Global Average | 2.62 s |

GTMetrix Test
GTMetrix test is based on the Google PageSpeed test. But with the GTMetrix test, we can get results from 7 worldwide locations. Also, with the results, we can get website performance score, TTFB, and fully loaded time.
Server Location | Performance | TTFB | Fully Loaded Time |
---|---|---|---|
Vancouver, Canada | 80% | 1.3 s | 2.3 s |
Hong Kong, China | 69% | 1.3 s | 3.7 s |

Load Test
With the Load test, we can know how much load any particular website or hosting can handle.
Response Times | 50 Visits/Minute |
Average | 3751 ms |
Minimum | 725 ms |
Maximum | 7319 ms |
Success | 50 |

WP Performance Test
The WP Performance test is based on two WordPress plugins, 1) WPPerformanceTester and 2) WordPress Hosting Benchmark tool.
WPPerformanceTester performs the following tests and allows us to see how any hosting server’s performance stacks up against industry benchmark. WordPress Hosting Benchmark tool test the server CPU, memory bandwidth, disk speed, and network download speed. After finishing the test, it provides a server score as a result.
Test | Result |
---|---|
Execution Time (lower is better) | 1.236 |
Queries Per Second (higher is better) | 809 |
Total Time | 11.060 |
Server Score | 5.7/10 |


Uptime Test
Uptime is one of the most important things in any hosting. Therefore, I measured the uptime of InterServer shared hosting for every one minute.
