ccache won&#x27;t help much if every TU changes with every typo fix - nothing but cache misses.  But yes, use ccache or similar to accomplish proper incremental builds.<p>As for link times: switch from bfd to gold.  And maybe play with --incremental.  I didn&#x27;t - just switching to gold shaved minutes off my link times for free, and suddenly link times were no longer my build bottleneck :)
