Does Bash Win 10 Take Too Long

Operating Systems

As a long-time user of both Windows 10 and Bash, I have often found myself frustrated with the time it takes for Bash to execute commands on Windows 10. The integration of the Bash shell within Windows 10 was a game-changer for developers, as it provided a way to use familiar command-line tools and utilities on a Windows machine. However, the performance of Bash on Windows 10 has been a topic of discussion and frustration among many users.

The Integration of Bash on Windows 10

When Microsoft announced the integration of the Bash shell on Windows 10, it was met with excitement from developers who had long relied on Unix-based command-line tools for their work. With the introduction of the Windows Subsystem for Linux (WSL), users could access a full-featured Ubuntu-based Bash shell without the need for virtual machines or dual-boot setups.

For me, this was a game-changer. I could seamlessly switch between my development work on Linux machines and my personal tasks on a Windows PC. The ability to run Bash commands directly on Windows 10 opened up a world of possibilities, from running shell scripts to using package managers like apt-get.

The Frustration of Long Execution Times

Despite the convenience of having Bash on Windows 10, I soon encountered a major frustration: the long execution times for certain commands. Simple tasks that would execute almost instantly on a native Linux system seemed to take an eternity on Windows 10 running Bash. For example, running complex scripts or using tools like grep and sed often led to noticeable delays.

At first, I thought the issue might be related to my specific setup or hardware configuration. However, after reading numerous forums and discussions, I realized that I was not alone in experiencing these delays. Many users reported similar struggles with the performance of Bash on Windows 10, especially when working with file I/O and process management.

Possible Causes and Workarounds

One of the primary reasons behind the slow performance of Bash on Windows 10 is the underlying architecture of WSL. While WSL provides a compatibility layer for running Linux binaries, it incurs overhead and translation costs that can impact performance. Additionally, the file system and I/O operations are handled differently between Windows and Linux, leading to bottlenecks when working with files and processes.

As I delved deeper into this issue, I discovered various workarounds that some users have found helpful in improving the speed of Bash on Windows 10. These include optimizing file system performance, adjusting antivirus settings to exclude WSL directories, and using alternative solutions for resource-intensive tasks.


While the integration of Bash on Windows 10 has undoubtedly been a positive step towards bridging the gap between Windows and Unix-based environments, the performance limitations have been a source of frustration for many users, including myself. Microsoft continues to make improvements to WSL with each Windows 10 update, addressing some of the performance issues along the way.

As someone who appreciates the seamless integration of different technologies, I remain hopeful that future updates will further enhance the performance of Bash on Windows 10. Despite the current challenges, the ability to use Bash within my familiar Windows environment is a valuable asset that has simplified my development workflow tremendously.
