## Rust Compiler Performance Triage
|
||
|
||
* [2020-11-10](https://github.com/rust-lang/rustc-perf/blob/master/triage/2020-11-10.md):
|
||
1 Regression, 2 Improvements, 2 mixed
|
||
|
||
A mixed week with improvements still outweighing regressions. Perhaps the biggest highlight was the move to compiling rustc crates [with the initial-exec TLS model](https://github.com/rust-lang/rust/pull/78201) which results in fewer calls to `_tls_get_addr` and thus faster compile times.
|
||
|
||
See the [full report](https://github.com/rust-lang/rustc-perf/blob/master/triage/2020-11-10.md) for more.

||
## Approved RFCs

Changes to Rust follow the Rust [RFC (request for comments) process](https://github.com/rust-lang/rfcs#rust-rfcs). These
