I flew down to our data center recently to decommission our ASA 5510's
replacing them with pfSense 1.2.3. Since then, I have noticed that we aren't
getting anywhere near the speeds that the ASA had been providing.
The average total throughput on the network is ~10MB/s, ~94%+ of which is
non-crypto.
When I initiate test downloads of large files, I start out with a ~3MB/s
speed which decreases rather steep on a linear scale to ~20KB/s. This is
true of HTTP uploads/downloads and scp uploads/downloads.
Also most of our ~4MB data sets (JSON) get truncated now, making them
unusable for our applications.
I've read a few posts that say setting these to 0 can help with the igb
driver:
dev.igb.1.enable_lro: 0
dev.igb.1.enable_aim: 0
If this is something I should attempt, do I truly need to reboot or can I
set these in the conf and run a sysctl -p without having downtime?
Any other thoughts?
TIA
