Do you have breakdown of programming time of each layer ex: orchagent or fpmsyncd/syncd?

| Bulking of Route updates will be enabled in Orchagent. Orchagent will bulk 64 updates and send to Sairedis. | ||
| A new timer will be introduced in orchagent to flush the outstanding updates every second. | ||

Bulking idea is nice but It introduces the delay for non bulk cases too. Can this timer tuned(starts off with low value and grow exponenetially, simiar to tcp)?

| | 5. | Clear mac table and check all routes and forwarding | | | | ||
