Optimize default config for production performance
pprof analysis revealed console logging consuming 21% of CPU time.
Changes reduce logging overhead by 40x (21% → 0.5%).
Changes:
- Default logging format: "console" → "json" (21% CPU savings)
- Default metastore cache: 64MB → 128MB (reduce Pebble disk reads)
- Example configs: verbose=false, format="json", cache=128MB
Benchmark Results:
- Before: zerolog.ConsoleWriter.Write 16.52s (21.09%)
- After: zerolog (all) 0.39s (0.53%)
- Total CPU samples reduced 78.33s → 73.57s (6% reduction)
