Tuneup Throughput cisco 6509-E

Hello Experts,

I have a question that maybe you can help with.

I operate a Cisco 6509-E Switch with T#show version
Cisco IOS Software, s72033_rp Software (s72033_rp-ADVENTERPRISEK9_WAN-M), Version 12.2(33)SXI3, RELEASE SOFTWARE (fc2).

I have a couple BGP sessions with two ISP's we only accept default route, advertise about 12 prefixes to both ISP.

ISP A: Cogent. 2x 10GB/s uplinks. BGP on a loopback

ISP B: Init7. 1x 10GB/s uplink.

I have default routes to both ISP's and OUTBOUND speed is just fine however, when i download a file, i cant get over 10 MB/s which is extremely odd.

I dont hace any ACL in place that can be affecting the Throughput and i have checked that internally, the Throughput is 1Gb/s from servers in Cabinet A trough C (A,B,C)

My config for the WAN links is as follows:

interface TenGigabitEthernet1/1
 description UPLINK WITH COGENT ID:*****
 ip address ip 255.255.255.252
 ip access-group EDGEDEFENSE in
 ip access-group INTERNALDEFENSE out
 ip tcp adjust-mss 1460
 ipv6 address ipv6/112
 no cdp enable
end

+++++++++++++++++++++++++++++++++++++++++

interface TenGigabitEthernet2/4
 description UPLINK TO COGENT ID:***
 ip address ip 255.255.255.248
 ip access-group EDGEDEFENSE in
 ip access-group INTERNALDEFENSE out
 ip flow ingress
 ip tcp adjust-mss 1460
 ipv6 address ipv6/112
 no cdp enable
end

+++++++++++++++++++++++++++++++++++++++++

interface TenGigabitEthernet3/4
 description INIT7 UPLINK HOTLINE: ****
 mtu 9216
 ip address ip 255.255.255.252
 ip access-group EDGEDEFENSE in
 ip access-group INTERNALDEFENSE out
 ipv6 address ipv6/126
 no cdp enable
end

BORDER01.RACKEND.NET#sho ip cef
Prefix               Next Hop             Interface
0.0.0.0/0            Init7-link        TenGigabitEthernet3/4
                     Cogent-link         TenGigabitEthernet1/1
                     Cogent-link        TenGigabitEthernet2/4

IP CEF is enabled, what else can i do to improve incoming bandwidth?

I see about 11GB/s of OUTBOUND traffic however, almost no incoming traffic at all.

Thank you for your advise

Ezequiel
