# Conclusions
|
||||
|
||||
Since the last measurement, both Dart Sass and LibSass performance numbers have
|
||||
improved. LibSass has made major strides particularly in processing dense
|
||||
extends, to the point that it's now faster than Dart Sass in those cases.
|
||||
This is the first measurement with Dart Sass running as ahead-of-time-compiled
|
||||
native code, and the results are encouraging. It's well below the 100ms
|
||||
threshold for tiny files, and it's on par with SassC for most test cases. SassC
|
||||
still leads for tests with many extends, although only slightly, and for one of
|
||||
our real-world test cases (although Dart Sass leads in others). The two
|
||||
implementations can be fairly described as having about the same performance
|
||||
overall.
|
||||
|
||||
Overall, Dart Sass on the Dart VM is still neck-and-neck with LibSass in terms
|
||||
of performance, and both are faster than they were at the time of Dart Sass's
|
||||
initial release. They're well within the parameters for highly usable systems.
|
||||
Dart Sass on Node is still substantially slower than on the Dart VM, and that
|
||||
relative slowdown becomes more pronounced as the raw Dart code becomes faster.
|
||||
Solutions for this such as [the embedded protocol][] or [WebAssembly support][]
|
||||
are becoming more and more important.
|
||||
|
||||
It's still the case that Dart Sass falls behind LibSass when processing small
|
||||
files—it's difficult for any VM to beat the startup speed of C++. But the app
|
||||
snapshot model means that it stays beneath the crucial 100ms limit for trivial
|
||||
files, which means it will look effectively instantaneous to humans.
|
||||
|
||||
Dart Sass on Node lags behind, particularly when many extends are in use. It's
|
||||
still faster than it was last measurement, but it would probably pay dividends
|
||||
to do some JS-specific benchmarking and optimization to try to bring the speed
|
||||
closer to that of the Dart VM. The majority of our users run Dart Sass through
|
||||
JS, so while it's good that they have a path to better performance with the same
|
||||
semantics, improving the baseline performance is important.
|
||||
|
||||
It's also still worth investigating the possibility of driving Dart Sass on the
|
||||
Dart VM through Node.js, ideally supporting the standard JS API surface. While
|
||||
this may add considerable overhead for custom functions, the gains in pure-Sass
|
||||
processing times may well be worth it for some users.
