Now under network load top lines in `top' are PID USERNAME PRI NICE SIZE RES STATE TIME WCPU COMMAND 10 root 155 ki31 0K 8K RUN 2:19 60.74% idle 11 root -72 - 0K 112K WAIT 1:47 32.03% intr{swi1: netis= r 0} And system is very responsive. ng_queue is not in top 17 (one screen) lines of `top' any more, it looks usual to me. I'll try to find revision, which breaks ULE + NetGraph by binary search, but it takes some time as here is 590 revisions in "head/sys" between previous version I used (which works Ok with ULE) and current version (which doesn't). So, it should be ~9 iterations, and every iteration takes ~1 hour and I could not spend 9 hours in row on this task. --=20 // Black Lion AKA Lev Serebryakov
