Microsoft new Outlook takes 10 seconds to do what Outlook Classic does instantly (windowslatest.com)

Article summary

Microsoft's new Outlook takes around 10 seconds to open a specific email from a notification, whereas Outlook Classic does it instantly. The new Outlook is built on WebView2, a Chromium-based rendering engine, which introduces performance limitations. The app's slow notification handling is attributed to its web-based architecture, which requires initializing or resuming its web layer, authenticating, and rendering the relevant mail thread. This issue is not easily fixable with an app update due to its underlying architecture.

What commenters say

• The new Outlook's slow performance is a result of its web-based architecture and the use of WebView2, which introduces unnecessary overhead.
• Microsoft's shift in focus away from Windows has led to a decline in the quality of its software, including Outlook.
• The use of corporate security tools and slow DNS systems can make Windows unusable, even for tasks that can be performed quickly in WSL.
• Some users believe that the slow performance of Windows is not just a technical issue, but also a deliberate design choice to make users work more slowly and reduce their productivity.
• Others argue that the performance issues with Windows are not unique to the operating system, but are also present in other corporate-provided devices, including Macs.
• There are concerns that the security community may eventually turn its attention to WSL, which could lead to exploits targeting the platform.
• Some users have found that disabling or uninstalling certain features in Windows 11 IoT Enterprise can improve performance.
• The cause of performance issues in Windows 11 can be complex and may require detailed analysis using tools like xperf and event tracing to identify the culprit.
