Why is it necessary to replace an ASA?
If the existing ASA does not have sufficient performance or processing capacity due to an increase in throughput or the number of simultaneous connections even if it is optimized, it will be necessary to replace it with a higher-level device or add an ASA. The following is an example of how to respond by changing the configuration.
Why is VPN throughput limited?
VPN throughput is the sum of transmission (tx) and reception (Rx).
Why is it important to check the number of VPN sessions?
There are several reasons why it is important to check the number of VPN sessions and maintain an appropriate number of sessions, but most importantly, as the number of VPN sessions increases, VPN throughput is shared among connected users. The available throughput per user is reduced. It is desirable to be able to provide business-free throughput, but if VPN access is concentrated and the number of users increases, the available throughput per user will decrease accordingly. However, it is usually necessary to provide each connected user with the minimum required throughput for performing business, even under the condition that access is extremely concentrated, even if there is delay or stress.
What is VPN throughput?
VPN throughput is the sum of transmission (tx) and reception (Rx). For example, in the case of TCP communication, while a terminal is downloading a file via the ASA (= Rx), there is also some communication (= Tx) of a confirmation response (ACK) from the terminal to the ASA.

The CPU usage rate increases as the number of encryption and decryption processes increases, so when the VPN throughput is close to the limit, you can almost always see a high CPU usage rate. Even if the same VPN throughput is generated, the CPU usage rate will be affected by various factors such as the products and functions used, the setting amount, the number of simultaneous connections, the traffic pattern, the usage version, and the environment.

Multi-context is a form of virtualization that allows multiple independent copies of an application to run simultaneously on the same hardware, with each copy (or virtual device) appearing as a separate physical device to the user.

VPN LAN2LAN (L2L) support for multi-context was added for the 9.0 release.

Problem
I have answered a lot of questions in forums, that are worded something like, “When I have a remote client connected to my firewall VPN they lose Internet access!” Traditionally that’s exactly what the ‘default’ remote VPN solution (IPSEC or AnyConnect) gave you.
Solution
At this point I’m assuming you have a remote VPN setup and working, if not you need to do that first, here are some walk-throughs I’ve already done to help you set that up.
Option 1 (Split Tunneling)
Rather than re-invent the wheel, I’ve already covered this before in the following article.
Option 2 (Tunnel All Split Tunneling)
1. Connect to the ASA > Go to enable mode > Then to global configuration mode.
