ESET FileScurity, MailSecurity Performance with Networkfilter - huge performance impact

[raimund 0]

Hi!

We see a huge performance issue on network-speed with networkprotection installled on Windows 2012 R2 Server. (with HyperV Role and VMs). When uninstalled, networkperformance was as expected OK.

Server HOST1 (HyperV enabled Role) has installed 2 x 10GBit NIC where NIC1 is patched to Switch (10G) and NIC2 to another Server HOST2 directly patched 10G.

Since the Networkprotection Feature was enabled/installed, the networkspeed significantly went down on NIC1, which is configured as hyperv-virtual-switch (parent partition allowed to share adapter as well).

On NIC2 copying between host1 and host2 over physical NIC2 was as expected 10G.
Strange is also, if copying data from one linux vm to another linux vm it seems ok, but to windows vm or host1 slow.

Notebook (1GBit) copying to server/vm with 66 MB/s when networkprotection was installed (no matter if enabled or not) - when unsinstalled speed constant 114 MB/s

We tested with iperf3, with networkprotection installed and enabled on host1, we never got more than 1,2G on 10G.
Could be an issue with networkprotection and hyperv-virtual-switch on windows server 2012 r2.

ESET and Windows Server 2012 R2 are up2date, also Drivers and Firmware.

I would recommend opening a support ticket with your local ESET distributor to find out if it's an issue that has been fixed recently and the fix will be included in EFSW v8.

You might want to temporarily test it with Endpoint v8. Uninstall EFSW, reboot the server and install EEA v8 to see if it makes a difference. If I remember correctly, you should get a warning that Endpoint should not be installed on a server system but you can ignore it and install EEA for testing purposes. After the test you can uninstall it and install EFSW 7.3 again.
