Hi Experts.<br />
<br />
What is happening is extremely frustrating.<br />
<br />
We recently upgrade our Junos on SRX650 from 10.2R3.10 to 10.4R9.1, and deploy a few servers.<br />
<br />
All the sudden, that network becomes extremely slow.<br />
<br />
Here is what we have in this network<br />
2x SRX650 in cluster running 10.4R9.1 with Web ,App and DB security zones.<br />
2x EX4200 in chassis running 10.2R3.10<br />
2 App servers in App zone<br />
2 Web VM servers in Web zone<br />
3 DB servers in DB zone.<br />
<br />
All the network connectivity seems slow between servers, through site-site VPN back to our main office.<br />
<br />
Please advise.<br />
<br />
Thanks,<br />
<br />
Jimmy

Network performance degradation after upgrading Junos on Juniper device and additional server deployment

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Network Operations includes asset management, help-desk supervision, security and user policies, infrastructure administration and anything else that affects the operation of your network. Discussions will include those of best practices in platforms, configurations, performance, security and accounting.
