What is Julia's compilation latency problem and how is it mitigated?

Julia suffers from first-call compilation latency, mitigated using precompilation, caching, and package images.

Because Julia is JIT-compiled, the first execution of a function includes compilation overhead. This can be noticeable in large applications. To reduce latency, Julia uses package precompilation, system images (PackageCompiler.jl), and incremental compilation caching. These techniques store compiled code ahead of time to reduce runtime overhead.
