Verified speed data for 18 rental servers
Reasons for choosing the speed test environment and tools
We used official WordPress themes for all measurements. We also installed WordPress unit test data on each demo site so that the text length and image sizes were the same.
This was measured with Google-provided
PageSpeed Insights
tools. We paid particular attention to TTFB (Time to First Byte). If the page's main content appears quickly, users are less likely to feel that the site is slow.
*For some items, we checked with developer tools rather than PageSpeed Insights.

The truth about server stability (uptime)
Uptime is an important indicator that is directly tied to business continuity. Many hosting companies guarantee 99.9 percent uptime, but actual measurements vary.
99.9 percent uptime means 8.76 hours of downtime per year, while 99.99 percent means 52.56 minutes. For an e-commerce site, even an hour of downtime can lead to sales losses worth hundreds of thousands of yen, so a difference of 0.09 percent still matters.

A Beginner's Guide to Understanding Rental Server Uptime and SLAs
Support coverage lets you check what hours phone, email, and chat are available. But you cannot know the actual quality of the support until you try it yourself.
You can confirm support coverage by checking whether phone, email, or chat support is available and at what times. But the actual quality of support only becomes clear once you use the service.
Personally, I found the support from Kinsta, ColorfulBox, Namecheap, and Hostinger especially courteous and quick.

The seven rules for choosing hosting without regret in 2025
1. Clarify your purpose before choosing. The required features differ greatly depending on whether you are building a personal blog, a corporate site, or an ecommerce business. Too much performance becomes wasted cost, while too little may force migration later.
2. Compare annual cost rather than initial fees. Many providers run campaigns that waive setup fees, but what matters is the total yearly cost. Be sure to factor in discounts based on contract length as well.
3. Always make use of the free trial period. Most hosts offer a free trial of around two weeks to 30 days. It is important to actually build a site and confirm the usability of the control panel and the real speed.
4. Check how complete the support system is. When technical problems occur, quick support matters. Confirm in advance whether phone support exists, what the hours are, and how strong the Japanese-language support really is.
5. Automatic backups are essential. Manual backups are easy to forget, and that can become critical when problems occur. Choose a server with automatic backups and make sure you understand the recovery process.
6. Think about future expansion. As your site grows, you may need to move to a higher plan. Confirm whether expansion is possible within the same service and how easy migration is.

The latest image optimization techniques
What Is a CDN? Improve Speed and Performance with a Network of Servers
Optimizing image files, which account for a large part of a website's size, is one of the most important steps for improving speed.
Optimizing image files, which often account for the largest share of a website's weight, is one of the most important parts of improving speed.
Effective optimization methods:
Use WebP format: reduce file size by roughly 25% to 35% compared with JPEG
Use responsive images: deliver the most appropriate image size for the visitor's device
Enable lazy loading: delay loading images that are outside the initial viewport
Optimize compression levels: balance image quality and file size

The key to cache settings
Five WordPress Plugins for Dramatic Speed Gains and Additional Performance Improvements
By configuring caching properly, you can dramatically reduce server load and improve display speed.
If cache settings are configured properly, server load can be reduced significantly and display speed can improve substantially.
Types of cache and configuration points:
Browser cache: temporarily stores files in the visitor's browser, often configured in .htaccess
Server cache: caches dynamic content on the server side
Database cache: temporarily stores database query results
Object cache: temporarily stores WordPress objects in memory
