It is plausible/expected that my version upgrade performance goes like (about 4K connections, long lived and short lived mix, TCP only, no HTTP:
1.5.12 (nproc 1, old connections causing about 100 old -sf processes to linger) uses 100% CPU almost all the time, frequently with >1 process. (100%, 75%, 48%, ... ). Highest CPU user has 2-3K connections. 1.8.1 (nbproc 4, with hard-stop-after 600s) using like 1%, 3%, 3%, 8% CPU Also 2-3K connections. Connect latencies much more stable. I started reading thru all the change logs, but extrapolating from that to our (all TCP-only, no HTTP) performance is taxing, thought I'd ask here first. Thanks, --Chris
