  Upgrading to a 64-core or 96-core AMD Ryzen Threadripper should theoretically trivialize build times. However, developers attempting to compile large Rust workspaces on these high-core-count machines frequently encounter system freezes, severe GUI lag, or sudden terminations by the Linux Out-Of-Memory (OOM) killer. Throwing 128 hardware threads at  cargo build  without architectural awareness often degrades performance rather than improving it. To optimize Rust compilation on workstation-grade hardware, we must address how  rustc , the LLVM backend, and the linker interact with CPU caches and system memory. Here is the technical breakdown of why a Threadripper struggles with default Cargo configurations and the exact steps to eliminate thread contention and prevent a Cargo build OOM. The Root Cause of Thread Contention and Memory Exhaustion By default, Cargo spawns one job per logical CPU core. On a 64-core/128-thread Threadripper, a standard  cargo build ...
