Zevenet CE - Thoughts

[satkas]

Hey
I tried to implement zevenet as a proxy for outllok.
My scheme looks like this:
Clients (different subnets)
--> zevenet-ce (farm https, l4xnat)
--> 3x exchange (backend on the same network as zevenet).
Zevenet Specs: Virtual Machine, 4CPU, 6GB RAM, Zevenet Version: CE v5.12.2
With a dozen or so users (about 200 connections) zevenet gives advice, but when I connected about 800 users, zevenet froze.

• It was impossible to display statistics via the GUI (the ball kept spinning until it finally gave up)
• the process for creating rrd files was turned on every 5 minutes and loaded 1 CPU in 100%
• the zproxy.cgi process was 100% when I wanted to display statistics in the GUI.
• In general, the load was small (several percent), and it was impossible to work normally in Outlook on the clients' side. The search took a very long time, the connections were broken, only to be reconnected after a dozen or so seconds.

How/Can Zevenet be configured to handle about 1500 clients (each client generates about 4 connections)?
