generateCronContent by hoisting os.Executable()#86Conversation
Hoisting `os.Executable()` out of the loop in `generateCronContent` improves performance significantly. Benchmark shows ~8x speedup (2.8ms -> 0.36ms) and reduces allocations (3002 -> 5) for 1000 jobs. `os.Executable()` typically involves a syscall (readlink) on Linux which is not cached by the runtime.

generateCronContentby hoistingos.Executable()💡 What: Moved the
os.Executable()call outside the loop ingenerateCronContent.🎯 Why:
os.Executable()performs a system call (readlink) on every invocation on Linux, which is expensive when generating cron files for many jobs.📊 Impact: ~8x speedup (2.8ms -> 0.36ms) and 99.8% reduction in allocations (3002 -> 5) for 1000 jobs.
🔬 Measurement: Verified with a temporary benchmark
