-## Portability
-
-Portable builds of Lighthouse are designed to run on the widest range of hardware possible, but
-sacrifice the ability to make use of modern CPU instructions.
-
-If you have a modern CPU then you should try running a non-portable build to get a 20-30% speed up.
-
-- For **x86_64**, any CPU supporting the [ADX](https://en.wikipedia.org/wiki/Intel_ADX) instruction set
-extension is compatible with the optimized build. This includes Intel Broadwell (2014)
-and newer, and AMD Ryzen (2017) and newer.
-- For **ARMv8**, most CPUs are compatible with the optimized build, including the Cortex-A72 used by
-the Raspberry Pi 4.
-
-## Troubleshooting
-
-If you get a SIGILL (exit code 132), then your CPU is incompatible with the optimized build
-of Lighthouse and you should switch to the `-portable` build. In this case, you will see a
-warning like this on start-up:
-
-```
-WARN CPU seems incompatible with optimized Lighthouse build, advice: If you get a SIGILL, please try Lighthouse portable build
-```
-
-On some VPS providers, the virtualization can make it appear as if CPU features are not available,
-even when they are. In this case you might see the warning above, but so long as the client
-continues to function, it's nothing to worry about.
