Overview

What is WinServer?

WinServer (by Assistup Inc.) is a rare specialist in the hosting world, dedicating its entire infrastructure exclusively to Microsoft Windows Server environments. As a Microsoft Gold Partner, they offer an unrivaled depth of expertise in Windows-based hosting, ranging from shared Plesk environments to sophisticated Virtual Desktop Infrastructure (VDI) for remote workforces. For Japanese businesses reliant on .NET frameworks, MS SQL databases, or Active Directory integration, WinServer eliminates the compatibility headaches often found with generalist Linux/Windows hosts.

Coefficient Applied

This hosting provider's website did not return full HTML content due to bot protection. HTML size was measured as 37KB (under 100KB). Since reliable "Time to 1MB" data could not be obtained, a +190ms coefficient was applied to maintain ranking fairness.

Coefficient Calculation Formula
penalty = (100 - 37) × 2 = +190ms
