Hello We are using the "new" Busyness method with 1.2.18 We have also using 'sticky sessions'.
Clarification on "> As soon as there will be real load, behaviour will differ." We have 9 nodes on 3 identitical servers with identical settings, lb factor equal on all nodes, but we see one node which had got a large MAX value (due to a large Busy number at some point), and one node that is not getting hardly any requests. Why such deviations please with "Busyness" ? Is it or could it be due to using 'sticky sessions' ? > mod_jk neither supports round-robin, nor random load-balancing. > > Currently you can choose between three algorithms: > > method=B (busyness): choose the worker with the lowwest number of > requests currently in processing. > > method=R (requests): choose the worker that did the lowest number of > requests until now > > method=T (traffic): choose the worker that received+sent the lowwest > number of bytes until now > > In case you use "busyness", you might observe behaviour that's very > close to round-robin during times of very low load.
