ESET SS firewall impacts network speed

Hi,

I have a PC running Vista x64 with a gbit ethernet interface connected to a Synology DS-508, all running at gbit speeds with jumbo frame support.

With ESET SS 3.0.672.0 installed, I tested the (SMB) file copy speed with the following results:

(1) Synology -> PC: 58 Mbps down, 0.7 Mbps up
(2) PC -> Synology: 111 Mbps up, 114 Mbps down



When I go to "Network and Sharing Center", LAN's "View status", "Properties", and untag (switch off) the "Eset Personal Firewall" and then copy files I get:

(3) Synology -> PC: 315 Mbps down, 1.6 Mbps up
(4) PC -> Synology: 349 Mbps up, 1.8 Mbps down


How can I get the same file copy speeds with the ESET firewall as now I have with the ESET firewall disabled? Are there settings that I should adjust or are these speeds simply not achievable when the firewall is enabled?

Thanks,

-Martijn



PS. It also puzzles me why the up and down speed in test (2) are almost identical. Anyone got an idea why that is?

 

ESET's firewall as with most firewalls will cause some impact to your speed, but never that much... I have a 8mbit connection and don't notice it.

v4 boasts to not affect speed so you could try that if you wanted, if not make sure you upgrade your ESS to 3.0.684.0

 

DNS gets slower

When I first installed ESET I did some testing. The only thing I could notice was that all addresses took .1ms longer to resolve over DNS. Other than that, I did not notice anything.

You will, however, notice a difference if you block HTTP addresses via Web access protection. Just disable it to see a performance spike.
