Hello.
I was recently blessed by my local carrier with an upgrade to 1Gbps - we have FTTH but they've just opened it up to 1Gbps. I was on 374_42 but had to upgrade because that version of code couldn't hit Gbps speed. I went to 378.54_2 and it worked perfectly. I've noticed that my NNTP sessions have been slower lately, and it hit me that they'd slowed down about the same time I upgraded to _55. I logged into the router while downloading and ran a top (I know, it's a huge resource consumer itself...but it works for troubleshooting) - anyway - I saw these two processes at the top of the stack. When the download completed the CPU went back to normal (<1%) and those processes disappeared back into the stack. I ran a speedtest and they popped back up.

I've disabled all of the Trend DPI stuff - even the filtering (there's a new bug in there somewhere...but I won't post about that now..I had to disable it earlier because it was blocking EVERYTHING on one of my kid's tablet) but the speed limit is still there. I can hit ~160Mbps via NNTP (using 50 active connections from a reliable usenet service). I'm just curious to know if those kernel processes should be consuming that much CPU and/or if there's anything I can do to increase the speed? Thanks
