It turns out that we use `UniversalMarker::pep508` quite a bit. To the point that it makes sense to pre-compute it when constructing a `UniversalMarker`. This still isn't necessarily the fastest thing we can do, but this results in a major speed-up and `without_extras` no longer shows up for me in a profile. Motivating benchmarks. First, from #10430: ``` $ hyperfine 'rm -f uv.lock && uv lock' 'rm -f uv.lock && uv-ag-optimize-without-extras lock' Benchmark 1: rm -f uv.lock && uv lock Time (mean ± σ): 408.3 ms ± 276.6 ms [User: 333.6 ms, System: 111.1 ms] Range (min … max): 316.9 ms … 1195.3 ms 10 runs Warning: The first benchmarking run for this command was significantly slower than the rest (1.195 s). This could be caused by (filesystem) caches that were not filled until after the first run. You should consider using the '--warmup' option to fill those caches before the actual benchmark. Alternatively, use the '--prepare' option to clear the caches before each timing run. Benchmark 2: rm -f uv.lock && uv-ag-optimize-without-extras lock Time (mean ± σ): 209.4 ms ± 2.2 ms [User: 209.8 ms, System: 103.8 ms] Range (min … max): 206.1 ms … 213.4 ms 14 runs Summary rm -f uv.lock && uv-ag-optimize-without-extras lock ran 1.95 ± 1.32 times faster than rm -f uv.lock && uv lock ``` And now from #10438: ``` $ hyperfine 'uv pip compile requirements.in -c constraints.txt --universal --no-progress --python-version 3.8 --offline > /dev/null' 'uv-ag-optimize-without-extras pip compile requirements.in -c constraints.txt --universal --no-progress --python-version 3.8 --offline > /dev/null' Benchmark 1: uv pip compile requirements.in -c constraints.txt --universal --no-progress --python-version 3.8 --offline > /dev/null Time (mean ± σ): 12.718 s ± 0.052 s [User: 12.818 s, System: 0.140 s] Range (min … max): 12.650 s … 12.815 s 10 runs Benchmark 2: uv-ag-optimize-without-extras pip compile requirements.in -c constraints.txt --universal --no-progress --python-version 3.8 --offline > /dev/null Time (mean ± σ): 419.5 ms ± 6.7 ms [User: 434.7 ms, System: 100.6 ms] Range (min … max): 412.7 ms … 434.3 ms 10 runs Summary uv-ag-optimize-without-extras pip compile requirements.in -c constraints.txt --universal --no-progress --python-version 3.8 --offline > /dev/null ran 30.32 ± 0.50 times faster than uv pip compile requirements.in -c constraints.txt --universal --no-progress --python-version 3.8 --offline > /dev/null ``` Fixes #10430, Fixes #10438
