1) Are there any performance issues with 6513 module core-switch and i wanted to know i have a sup 720B in this core-switchwhich 720Gb/sc throughput does it mean it is switching throughput or Routing?
The 720 Gbps is the fabric (duplex) bandwidth capacity.
Yes there are many possible performance issues, especially as you're configured.
Sup720 only provides (in a 6513) 40 Gbps to slots 9-13, other slots are only 20 Gbps.
Non-CEF256 cards are either 32 Gbps (duplex) shared bus (6148) or 8 Gbps to the fabric (6548).
Classic bus cards (6148) can not directly communicate with CEF720 cards (67xx). Data has to be relayed through the sup.
I recall (?) 65xx cards with both fabric and bus connections have a static option whether to transmit using their fabric or bus connection. Default might be to use bus connection, in your chassis fabric connection likely better as most of your cards have fabric connections.
Any classic bus card in the chassis limits sup's packets-per-second performance. Sup720 is rated 15 Mpps in non-Compact mode or 30 Mpps in Compact mode (your running in truncate mode). Also 30 Mpps is documented for all packet sizes, so performance difference might be much, much more than 2x.
Older line card often have much more limited performance per port, i.e. ports groups share buffers or ASICs.
The Sup720 performance PPS performance is shared by the whole chassis unless you also have dCEF (DFC) cards. (Your 6708 has a DFC, standard.)
Minimum size Ethernet packets requires 1.455 Mpps per 1 Gbps, so 15 Mpps is might max out with as little at 5 Gbps (duplex).
2) I guessall CEF 6748 module must have 40G spedd below ,Please correct me if i am wrong?
They have that much bandwidth to the fabric (as also noted by Reza). To take full advantage of it, you need to account for much else (see above).
PS:
Suggestions:
Resolve issue with 2nd sup - doesn't appear to be in correct standby mode. (Won't change performance but if active sup fails . . .)
Replace the classic bus card (6148) with a fabric card. (I.e. get chassis to run in compact mode.)
When working with high density gig, avoid using all but 67xx line cards. (Note: Your 6524 is a non-issue, as it's only 24 FE ports with 8 Gbps fabric.)
Move 6724 card, if possible, to 20 Gbps slot. (I.e. reserve your 40 Gbps slots for cards that require 40 Gbps.)
PPS:
For even more performance, as it appears all your CEF720 cards but the 6708 are CFCs, you can selectively install DFCs or you can upgrade your Sup. Both the VS-S720 and Sup2T provide higher centralized PPS. (Sup720s, I believe, are EOL.)
