After searching serverfault for similar questions without success, these are my numbers for one magento instance, running on multiple servers:
After varnish about 4 requests per second hit the webservers
The magento cache is configured to use one separate memcache server where I'm measuring about 210 Mbit/s bandwith usage.
Compared to other projects, magento and non-magento, this number seems way off (as in extremely high).
I'd like to get some data to compare to, or even better, if you have any idea what exactly causes this/how to find it and how to improve the situation.
