Dear Tech Team,
I configure 3750 stack switch as core and 2960 stack switches as access layer switches.
I connected my laptop to one of my core stack in VLAN 10 and I am pinging to one of my server in VLAN 1.
Can someone say me what will be the minimum latency at the time of inter VALN routing
Thank you Team.

When you ping from your PC, it will show you the time that it takes. In this case is 1ms.
Pinging 192.168.1.5 with 32 bytes of data:

Hi Krishna,
less then or = to 1 ms If you there is no congestion.

Minimum latency depends on forwarding performance of each switch, bandwidth of each port, congestion, cut-through or store-and-forward forwarding, size of frame, distance between switches, and number of hops. Since you also mentioned a 3750 stack, depth of stack would also likely impact latency.
However, on non-congested 2960 <> 3750 stack <> 2960, as the other posters have noted, you're latency is likely to be under a millisecond.
PS:
BTW, normal pings between hosts wasn't designed for high timing accuracy.
