We have a cluster of 3 x Ironport S370's all running 7.7.0-753
The throughput is really poor we have a 500Mbps Internet connection which at it's peak is only getting to 120Mbps as the Ironports don't seem to be able to handle the traffic.
The Proxy CPU% is always close to 100% but the overall CPU is usually at no more than 30% at times it can take up to 60 seconds to load the initial page particularly if the site is an HTTPS site.
We have
22 Identities
62 Access policies
6 decryption Policies
Our maintainer says that having this number of Identities / policies should not be an issue but I have my doubts.
Can anyone advise as it's really become a major issue, Output from the rate and status commands are below.
