# MONITORING RECOMMENDATIONS:
|
|
# - Monitor CPU usage on cores 0-1
|
|
# - Track memory usage (should stay under 2GB)
|
|
# - Monitor PostgreSQL connection health
|
|
# - Set up alerts for service restarts
|
|
# - Monitor trading latency metrics via logs
|
|
#
|
|
# PERFORMANCE NOTES:
|
|
# - Dedicated CPU cores 0-1 for minimal latency
|
|
# - High priority scheduling (Nice=-10)
|
|
# - Real-time IO scheduling
|
|
# - Memory lock capability for performance
|
|
# - No address space randomization for consistency |
