Whilst playing with a small, but fast, berkely DB based transaction server; which sits on a tcp/ip socket connection I ran into sometimes unpredictable reply times. One of the major problem was solved by increasing the MSIZE to 256 (the 103 bytes+ delayed ack problem). Now recently I came across: http://www.scl.ameslab.gov/Projects/Gigabit/performance/prelim.html Now could any one explain to me WHY freebsd appears so unpredicatable ? i.e. not a nice S-curve ? Is that the way of measuring ? Some other artifact, or real ? I think it is real, as I get the same sort of holes in my graphs for the transaction server. Any chances on an expose....
