Cisco 2900 WAN performance

We want to buy a new router and I'm searching for the best option.
For Cisco routers I have found the 2900s series interesting but I was astounished to see that the WAN performance is only up to 75 Mbps
"They deliver virtualized applications and highly secure collaboration through the widest array of WAN connectivity at high performance that offers concurrent services at up to 75 Mbp"
http://www.cisco.com/en/US/products/ps10537/index.html
Does that mean that if we are connected to a symmetrical 100 Mbit Internet connection the router would only support up to 75 Mbit? Is it for every seperate connection or all connections. How is the (theoretical) performance if you have only one connection (e.g. an FTP upload)?
If I need more would I have to upgrade to the 3900s series?
Greetings and thanks

The reason for ISR "low" performance, they (and their predecessors) were really designed for being feature rich while working with "low speed" serial WAN links. Traditionally, 75 Mbps would be a rather fast WAN link.
Today WANs, running at LAN like speeds, often are LAN like media hand-offs, i.e. Ethernet. Cisco does have a line of MetroEthernet L3 switches, feature poor compared to ISRs, but they offer LAN forwarding performance.
In any case, the "fastest" 2900, the 2951, is Cisco recommended for up to 75 Mbps WAN bandwidth. As you note, this allows for "concurrent services". ISR performance depends very much on average packet sizes and how the router has been configured. At the other extreme, the 2951 is documented as being able to push 5 Gbps, with no services and with maximum size packets. Cisco recommendations are conservative, which means a 2900 series might be perfectly fine on your 100 Mbps link, or might not too. Much would depend on you configuration and what your traffic is like.
Cisco recommends the 3925 for up to 100 Mbps of WAN bandwidth.
I've attached a Cisco whitepaper, which provides much more information about ISR performance.

CISCO 2900 loses NAT

Hi,
I have CISCO 2900 series router which i use it in our ISP setup. The router has more than 250 static NAT configured on and a about 70 routes. The problem is, every after a while a random NAT disappers from the router. In show run one NAT goes missing. If i added the NAT i get a message that the NAT already exist. So i have to remove the NAT and then add it again for it to appear again but nowadays i just clear the NAT translation (clear IP NAT translation *) and it apppears.
Any ideas on what could be the problem here?
Thanks,
Abbas

Thanks for the suggestion Elton.
Unfortunately, I believe the LAN ports on this router are layer 2 only, thus they will not take `ip nat` configuration:
Router1(config-if)#ip nat enable
                      ^
% Invalid input detected at '^' marker.
Router1(config-if)#ip ?
Interface IP configuration subcommands:
address     Set the IP address of an interface
admission   Apply Network Admission Control
auth-proxy Apply authentication proxy
ddns        Configure dynamic DNS
device      IP device tracking
dhcp        Configure DHCP parameters for this interface
igmp        IGMP interface commands
rsvp        RSVP Interface Commands
vrf         VPN Routing/Forwarding parameters on the interface
Here's the result of `show IP NAT translations` as requested:
Router1#show ip nat translations | include ---
tcp 188.222.181.173:25    192.168.1.2:25        ---                  ---

Router1#
As the rules are setup as NVI type rules, they should not be showing up in the command above, instead they should show up in return to the following command:
Router1#show ip nat nvi translations
Router1#
Any ideas why this would happen?

WRVS4400N WAN-LAN-WAN Performance

Hi
i'm searching for a router that can handle Gbit Connections. that means, ich hab 1 gbit port from my provider and i want to use more than 1 device --> router
at this page:
http://www.smallnetbuilder.com/component/option,com_chart/Itemid,189/chart,121/
the rvs4000 where tested, but the wan->lan performance was poor.
i saw at the release notes of an firmware update, that this problem was fixed.
is the WRVS4400 and the RVS4000 the same device but with WLAN ?

2900 router performance

Which of the 2900 series routers would provide at least 2-3 times the performance of a 2811? This router will be used to support connectivity for approximately 65 remote sites that each have a T1 into an MPLS cloud.

Reza's second references would let you compare PPS ratings, so, for example, a 2911's 353 Kpps is about 3x a 2811's 120 Kpps.
Reza's first reference would let you size based on expected usage and WAN bandwidth (its bandwidth to your MPLS cloud).

Cisco ASA 5505 performance issues on downloads - data into the ASA from the Internet

I have having serious issues with performance on my ASA 5505s that I am testing with 9.2.3 code.
I stripped the config and removed as much stuff as I could - no VPN etc. and I am ONLY getting about 30-40Mbps downloads from sites but 95Mbps uploads???? Anyone else seeing these problems? If I remove the firewall my PC can hit 300/300Mbps to the same sites using the same switch and cable.
I installed 1Gb of mem on the ASA 5505 but it made no difference. The ASA has a UL IP Security license but I am only using and inside and outside address for these tests, no other ports configured.
Is anyone else seeing this performance problem with the 9.2.3 code? I went to this from 8.2.5 to try to resolve QOS failure bugs that I found in the 8.2.5 code. I did not expect to have a performance hit though and it is only on downloads TO the ASA from the Internet from all speed test sites that I try. Uploading speeds seem fine. No access-lists on my interfaces either...barebones config.
My FIOS and switch interfaces are fine...no errors on any interfaces and the same switch interface hits 300/300Mbps when my laptop is directly attached.
Anyone have a barebones config on their ASA 5505 that flies...I will try it on mine and see if some command somewhere (hidden) is causing the issue. I even cleared the config and started with a clean slate just in case I was missing some command from the older configs that may have impacted performance.

After changing the switch with a high end switch my performance increased but I am still not happy with the throughput out of my ASA. I have about 50+ ASAs 5505s and a dozen 5510s. Most remote sites have 5505s. All my sites right now have 8.2.5-51 and I wanted to put 9.2.3 out there to solve issues I have uncovered on the 8.2.5 code with regards to QOS issues.
I get much better results using the Cisco 3750X attached to the FIOS (right around 300/300 with my laptop directly attached to the 3750x bypassing the ASA - my FIOS circuit rating is also 300/300). Going through the ASA to the same test site I get download speeds of 35 to 75. Changes randomly which really bothers me. My uploads speeds are ALWAYS faster then my download speeds. Example - best download I would ever get is 75Mb and my upload would usually hit 95Mb during the same test period.
I may have to live with it but the inconsistency is what really bothers me.
Here is the config I am currently using. Nothing going on during testing since only a single PC is attached. VPN tunnel to the main site can be up or down...doesn't seem to make any difference. PC does to site directly from outside interface of ASA...split tunneling. Even when I removed tunnels and tested with just the ASA as a firewall to the Internet I was still seeing the same inconsistencies.
Anything obviously missing - new command or anything? Xlates causing issues?

Cisco Gigabit 3504 Performance

I have a Cisco Gigabit 3504 to which all the uplinks of my switches are connected.The bandwidth utilization when monitored is 0.7% and the users report slow performance despite connected directly to the switches.CDP,SNMP etc are disabled and the switch is running on minimal configuration.What are the steps to follow and how can i increase the performance so that the bandwidth of the gigabit is utilized and the increase Network Performance.

You should implement etherchanneling (bundling multiple links for bandwidth aggregation).
Disabling CDP and SNMP won't augment your performance.
Can we see the switch configs ?

Cisco WAE boxes performance

Is there any difference in the performance optimization done by WAE512 and WAE612 devices or is that 612 does the same factor of WAN optimization for various protocols with more connections

The differences is basically processing power, disks and memory. However, the actual optimization would be roughly the same for similar traffic. The 612 uses the same software and compression technology as the 512.
So in WAAS 4.1.x, with all the AO enabled: the 512 (depending on memory options) can handle maximum optimized tcp connections from 600 - 1200. The 612 (again, depending on memory) supports 1600-4800 connections.
Obviously the 612 has more horsepower and can be used in larger offices and for larger WAN links.
Hope that helps,
Dan

Cisco 888 VPN performance

Hi all,
Cisco 888 have 4-port 10/100-Mbps managed switch and supports many types of VPN.
But I cann't find VPN performance in Mbps in Cisco documentation.
How much is that for AES256+SHA-1 ?

Cisco ASR 1002- performance issue due to access list

Hi,
We are planning to implement inbound access-list to block subnets from particular country. Since the subnets are not contiguous, we have about 16000 lines of acl entries.
I want to know, would there be any performance or latency issues after applying 16k lines of acl?
Is there a good document where I can read more about ACL limitations and performance issues on ASR.
This is for ASR1002, running IOS-XE 15.3(1)S1.
Thanks

Sorry, I don't know the answer to your questions, but I'm writing to mention a 7200 feature, that if supported on the ASR, might help in your situation. See http://www.cisco.com/c/en/us/support/docs/security/ios-firewall/23602-confaccesslists.html#turbo

Cisco 2900 compatible with VWIC-1MFT-T1?

Can a VWIC-1MFT-T1 card be used in a 2900 series router? The compatibility tables on Cisco seem to indicate that it is not compatible, but are not definitive. Anyone ever tried to put one of these in a 2900?

No, you need VWIC2-MFT or VWIC3, see the compatibility reference:
