Think not only throughput but about pps also.According to cisco doc ESP40 has ~24Mpps capacity, ESP20 has the same limitation.
So, you pick out all resources from QFP.RA write the report where you can see this limitation - http://www.slideshare.net/RouterAnalysis/cisco-asr-1000-series-testing-results-and-analysis

Pete, Thanks for this - I'll watch that preso and see if it adds anything useful. You seem to be supporting my viewpoint, and I've also had an off-list reply supporting TAC's viewpoint - so I'm not sure I'm any further forwards. I'm currently working on a plan to replace the ESP40 with an ESP100 - but as the ESP100 isn't supported in the ASR1004, I'll also have to do a chassis swap to an ASR1006. My only remaining concern with this plan is whether the SIP40 can really do 40Gbps. If I stick 4 * 10G SPA's into a SIP40, can I run those 10G ports at line-rate (assuming sufficient ESP capacity)?

The SIP could also be a limiting factor, but since you are split between SIPs that shouldn't be an issue. The SIP 40 has 2x 40Gig lanes on the backplane. Are you doing crypto or anything like that which would impact performance? There is a great Cisco Live preso on the ASR1k architecture that might help you get some ammo to go back to TAC with. http://d2zmdbbm9feqrf.cloudfront.net/2014/usa/pdf/BRKARC-2001.pdf -Pete On Sat, Oct 4, 2014 at 4:56 AM, Simon Lockhart <[email protected]> wrote:All, I'm banging my head against a brick wall trying to get sensible answers from Cisco TAC, so thought I'd ask the educated masses who may have come across this before... I've got a Cisco ASR1004 with RP2, ESP40, 2 * SIP40's, and 8 * 10GE ports. A snapshot of usage on these ports at peak is: Interface RxBps RxPps TxBps TxPps Te0/0/0 4,385,563,000 515,508 906,118,000 339,997 Te0/1/0 3,942,338,000 419,696 984,150,000 358,436 Te0/2/0 3,949,993,000 425,192 933,257,000 349,145 Te0/3/0 4,375,526,000 512,858 873,284,000 334,751 Te1/0/0 1,186,440,000 454,714 5,474,029,000 630,916 Te1/1/0 622,154,000 244,056 3,181,689,000 338,190 Te1/2/0 711,493,000 253,275 3,211,560,000 340,950 Te1/3/0 1,218,873,000 437,195 4,831,708,000 568,488 TOTAL 20,392,380,000 3,262,494 20,395,795,000 3,260,873 I'm seeing throughput issues on a portchannel consisting of Te0/0/0 and Te0/3/0 (it won't go over 10Gbps aggregate) Cisco TAC are telling me if I add TxBps and RxBps totals together, I get 40Gbps, so I've reached capacity of the QFP (i.e. ESP40). My arguement against this is that a packet which enters the router on Te0/0/0, goes through the SIP40 in slot 0, through the ESP40, through the SIP40 in slot 1, and out through Te1/0/0 is still just one packet, so should only need to be counted once through the ESP, and once for each SIP. Hence, the throughput on the ESP is only 20.3Gbps on those numbers above. If I poll ceqfpUtilProcessingLoad by SNMP, I see peaks of around 65%, which would correlate with this level of throughput. I'm assuming there are others of you using this platform. What sort of throughput are you seeing? Am I right, or is the Cisco TAC engineer?
