Hoisting the os.Executable() call outside the loop in generateCronContent avoids repeated system calls for every job. Benchmarks show an ~8x improvement for 1000 jobs: Before: ~2.85ms/op After: ~0.36ms/op This optimization reduces CPU usage and latency during cron file generation, especially for configurations with many jobs.

This PR improves the performance of the
generateCronContentfunction by hoisting theos.Executable()call outside of the job iteration loop.Why
os.Executable()performs a system call (e.g.,readlink /proc/self/exeon Linux) which is relatively expensive. Calling it for every job in the list is unnecessary as the executable path does not change during the loop.Impact
Benchmarks (
