System Mechanic NetBooster Continues to Find New Ways to Unleash Net Speed

The System Mechanic® NetBooster® internet optimization feature offers several new ways to help users achieve the fastest internet speeds. For example, iolo engineers have discovered no less than eight unnecessary Windows® 10 services that needlessly burden broadband speed. In addition, new changes to a dozen TCP settings are now recommended to ensure better streaming, gaming, downloads and more.

  • Automatic Internet Optimization Since Windows 10 recently deployed significant changes to the TCP settings, System Mechanic has identified new optimal settings for improving network speed. The new optimal settings are:
    TCP Global Parameters

    Receive-Side Scaling State

    : enabled

    Receive Window Auto-Tuning Level

    : normal

    Add-On Congestion Control Provider

    : ctcp

    ECN Capability

    : disabled

    RFC 1323 Timestamps

    : disabled

    Initial RTO

    : 3000

    Receive Segment Coalescing State

    : enabled

    Non Sack Rtt Resiliency

    : disabled

    Max SYN Retransmissions

    : 7

    Fast Open

    : enabled

    Fast Open Fallback

    : enabled

    Pacing Profile

    : off

    Many applications—especially torrent clients, web browser plug-ins and third-party download managers—change these settings to accommodate their own server configurations. This results in degradation of overall internet speed, typically experienced as slower website loading. NetBooster discovers and reverts these setting changes to re-optimize internet speed.

In addition to NetBooster’s Automatic Internet Optimization feature, the following Windows settings and services can be disabled or adjusted in the NetBooster Advanced Settings wizard.

  • Windows Update Delivery Optimization

Enabled by default in Windows 10, Microsoft’s Windows Update Delivery Optimization includes peer-to-peer technology similar to that used for torrent file sharing. When fully enabled, Windows 10 will periodically download updates and share them over the internet with other users. This Windows feature is not easily disabled in Windows 10, and can be a significant drain on network speed.

System Mechanic will determine for you if WUDO is enabled, and allow you to disable it easily from the NetBooster Advanced Settings wizard.

  • Network Reservable Bandwidth Limit

This Windows setting determines the percentage of bandwidth that the system can reserve. This value limits the combined bandwidth reservations of all programs running on the system. By default Windows 10 reserves 80% of the bandwidth; therefore if any system networking operation is started, all user network activities are limited to 20% of total bandwidth until the system completes the operation.

  • Unnecessary Windows Network Services

The following are optional Windows services that adversely affect network speed. All of these start automatically in Windows, and turning them off will not compromise system function:

  • Diagnostic Policy Service
  • Distributed Link Tracking Client
  • Offline Files
  • Performance Logs & Alerts
  • Program Compatibility Assistant Service
  • Secondary Logon
  • Windows Error Reporting Service
  • Windows Image Acquisition (WIA)

System Mechanic can determine which of these are enabled, and allow you to disable them all easily from the NetBooster Advanced Settings wizard.

In these ways, System Mechanic continues to keep apace with Windows as it evolves. Yesterday’s problems may not be around tomorrow, but new ones are sure to keep iolo engineers busy, delivering you the fastest, most stable and secure computing experience possible.
