SEP 12.1.4: Extremely poor firewall performance
Interesting issue I just discovered. I'm not sure if this is new or not, or unique to 12.1.4 or not. I've been having problems deploying SEP remotely to clients (whihc is posted to another thread I"ll reply to soon) but I wanted to get one PC up and running with SEP using any means necessary. So I created the single exe packgae from SEPM with the intent of copying the file from the server (2008 R2) to the PC (Win 8.1 Pro).
After testing serveral times, here are my conclusions:
- if SEP is ON, on the server, my file copy speed varies between 300KB/sec to 1.0MB/sec, absolutely terrible
if SEP is OFF (right-click system tray icon, choose Disable Symantec Endpoint Ptoection), my speed goes instantly to 100+MB/sec.
I've done this a number of times and it is consistent. The file can even be in mid-copy and as soon as I turned of SEP client on the server the network copy speed skyrockets.
This is a default install of SEP, using the default features/package from SEPM. I"m not sure if I've modified the firewall yet so I can check that but is my first step to determine if it is indeed the firewall, and not say, real time antivirus scanning?
Has anybody seen this issue?
