Matthieu Simonin updated DISPATCH-957: -------------------------------------- Attachment: mem_usage_idle_25_min.tar.gz > Unbalanced memory consumption in a 2 routers configuration and specific > workload > -------------------------------------------------------------------------------- > > Key: DISPATCH-957 > URL: https://issues.apache.org/jira/browse/DISPATCH-957 > Project: Qpid Dispatch > Issue Type: Bug > Components: Router Node > Affects Versions: 1.0.1 > Environment: * At the time I was experimenting, I built the router > from the source and > used 22400df dockerized. It's available in docker hub : > msimonin/qdrouterd:22400df or msimonin/qdrouterd-collectd:22400f > > * ombt version used embeds the following library > oslo.messaging==5.35.0 > pyngus==2.2.2 > python-qpid-proton==0.19.0 > > * I used ombt-orchestrator to deploy all the stack using the g5k provider > (see > https://github.com/msimonin/ombt-orchestrator/) In a local machine setup, > vagrant provider can be used but I'm not sure if it is reasonnable to scale > the > above number of agents. I've attached nevertheless the configuration used. > > * Host Linux distribution is debian9 > > > Reporter: Matthieu Simonin > Assignee: Ken Giusti > Priority: Major > Attachments: call.png, cast.png, conf.yaml, conf.yaml, inc-calls.png, > mem_usage.tar.gz, mem_usage_idle_25_min.tar.gz, router0.log, router1.log > > > After discussion with Ken Giusti we deem appropriate to fill a bug to track > the > following behavior. > Note also that the exact version used in the following description isn't > exactly 1.1.0 but one built from source 22400df (master back in february). > I started two interconnected routers (router0 and router1) > router0 is where all my consumers connect router1 is where all my producers > connect . > The workload is an RPC test using oslo.messaging library using calls > (resp. casts) : clients keep sending message and block for the response > (resp. do not block). > I've attached some observations: > 1) > With 100 consumers and 100 producers and calls I observe a higher memory > consumption of router0 in comparison of the memory consumption of router1 (see > calls.png). Casts seem to less affect the router memory. Calls usually > requires > more ressources because of the return values flowing back to the producer but > I wouldn't expect this big difference. > I've attached a tgz in which, you'll find the results of qdtsat -a,-m,-l > * before the benchmark (start) > * early during the benchmark (during) > * late during the benchmark (during-1) > * after the benchmark completed (after) > 2) I've run a second test increasing incrementaly the (#clients, #servers) : > [50, 100, 200, 500] (calls only) > see inc-calls.png > in this case the difference of the memory consumption between router0 and > router1 is [50MB, 100MB, 300MB, 1.5GB] -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
