[rabbitmq-discuss] Management UI performance with 3.3.1 on OSX

[Gavin M. Roy]

I believe I’ve traced it back to DNS. When I override the work provided DNS servers with Google’s Public DNS, everything behaves as expected. Reviewing release notes now to see if anything mentions changes with regard to DNS lookup.

I've been using the latest standalone release this whole week "out of the tarball" with the management plugin, and I haven't seen any issues.

I haven't tried using homebrew, tho.

Hey,

I just updated from 3.2.4 on OSX to 3.3.1 via homebrew and the Management UI performance is pretty terrible (8 to 16 seconds per API call). http://i.imgur.com/iIEzi7a.png demonstrates the issue pretty clearly.

There’s nothing of note in either of the log files and 3.2.4 ran just fine. I’m just running this with defaults, no rabbitmq.config file.

I have Erlang R16B3 installed, but noticed that the homebrew install has a bundled R16B2. 

I doubt it’s erlang version related however, as I manually built 3.3.1 from rabbitmq-public-umbrella and am experiencing the same issue. 

I’ve also noticed that startup is significantly slower than I am used to. 

Note that compiling v3.2.4 manually and running it makes the problem go away. In each compile test,  I’d nuke the data directory to ensure it’s not some issue with the previous mnesia data.

I’m not encountering an issue with 3.3.1 on linux, and I do not see any similar slowness with any other applications.

Thanks in advance,

Gavin
