*Subject:* Performance Issue: Sub-optimal resource utilization with growing
graphical asset library

*Hello Tux Paint Development Team,*

I am writing to bring to your attention a performance issue I've observed
in recent versions of Tux Paint. I believe this is a more advanced,
architectural problem rather than a simple bug, and I wanted to explain my
findings in detail.

*Problem Summary:*

With each new version of Tux Paint, the collection of graphical assets
(stamps, brushes, magic tools) grows significantly. This is fantastic for
user creativity, but I've noticed that the software's performance,
particularly in terms of loading times and responsiveness when interacting
with these tools, appears to be capped. My observation is that even on
high-end hardware with a fast multi-core processor, a substantial amount of
RAM, and a fast SSD, Tux Paint does not seem to utilize the full system
potential to load these assets quickly. Instead, it seems to be limited to
a specific, lower amount of resources, which can lead to a less-than-ideal
user experience.

*Specific Observations & Examples:*

   -

   *Loading Times:* When launching Tux Paint for the first time after an
   update, or when a large number of stamps are added, the initial load time
   is significant. This seems to be due to how the application handles and
   caches these files, rather than a limitation of the hardware.
   -

   *Asset-Heavy Tools:* The "Stamps" and "Magic Tools" with extensive
   libraries can feel sluggish or have a noticeable delay when switching
   between different categories or applying them to the canvas.
   -

   *Hardware Underutilization:* Using system monitoring tools, I've
   observed that during these performance-intensive moments (like initial
   loading), CPU usage often remains low on a powerful multi-core machine, and
   disk I/O is not saturated. This suggests the bottleneck isn't the hardware
   itself, but a limitation in how the software is written to manage and
   process these assets. It's not taking advantage of parallel processing or
   other modern optimizations.

*Proposed Solution:*

I am not asking for changes to the user interface. My request is focused on
the core codebase. I would like to suggest that the development team
consider a refactoring of the code that handles the loading, caching, and
management of graphical assets. The goal would be to allow the software to
make better use of modern system resources, such as:

   -

   *Multithreading:* Using multiple CPU cores to load assets in parallel,
   dramatically reducing startup and tool-switching times.
   -

   *Optimized Caching:* Implementing a more efficient caching system that
   can handle a large volume of files and quickly retrieve them without
   hitting performance roadblocks.
   -

   *Hardware Acceleration:* Exploring the use of hardware acceleration
   (GPU) for rendering and processing graphical tools, where appropriate, to
   offload work from the main CPU.

I understand that this is a significant and complex request, as it involves
fundamental changes to the software's architecture. However, as Tux Paint
continues to grow and add more wonderful content, these optimizations will
become increasingly important for maintaining a smooth and responsive
experience for all users, particularly those with powerful modern computers
who expect the software to run at its full potential.

Thank you for your time and for all the amazing work you do on Tux Paint.
