Will do. I’m tracking down the latest commit where adding request_paint back still fixes this issue. Will post to GH with all of this info today.
Thanks Bryan

Dan,
Can you make a GH issue with this new information? That will make it easier to engage other devs in the discussion.

The change below, in line 531 of
bokehjs/src/coffee/models/plots/plot_canvas.coffee
is the culprit of my long delay for figure updates. I installed Commit 3edfdaf0913b523def90ec1fcc84943cdb371a2e (which has long delays in my figure updates), but manually changed line 531 back to @request_paint(), and the lag went away.
- @request_paint()
XXX: can’t be @request_paint(), because it would trigger back-and-forth
layout recomputing feedback loop between plots. Plots are also much more
responsive this way, especially in interactive mode.
- @paint()

I evaluated the javascript console log using trace log level and isolated all messages with an elapsed time of > 1sec not due to delays in user interaction (i.e., i waited a few minutes in between clicking a button or drop down).
All of the delayed messages happen in data_range1d.js and glyph_renderer.js… with only one in session.js
I know this still isn’t quite enough to go on for you. But wanted to share. My next plan of attack is to install various commits to see if i can isolate a specific commit, and maybe even some code… might take a while.

That feature might be helpful.
It’s still very peculiar to me that 0.12.10 is very smooth with all of these objects.
I’ll keep poking around and let you know what I find.
Thanks Bryan

That’s probably too much for Bokeh’s layout constraint solver, since everything gets considered together. (Though that is only speculation at this point) The next release will have the ability to place individual server app items in templates, so that reliance Bokeh’s layout system can be minimized or avoided.
Thanks,

The slow down appears to occur in the browser. If I turn off the bokeh server after the terminal has indicated all data updates have been completed, my browser will eventually display the changes.
I have 9 tabs, each with lots of objects in each. The webpage is relatively quick if I cut that down to 2, no one tab appears to be the sole culprit. But still slower than 0.12.10. My concern is that Bokeh 0.12.10 can handle all of these objects in one document perfectly fine.
I’m using:
Chrome Version 64.0.3282.186 (Official Build) (64-bit)
Mac OS 10.13.3WiIl update if I find more and post simple code on GitHub if I can.

This issue persists in 0.12.15. The software I’ve built is basically unusable for Bokeh >0.12.10.Are there any methods to print an activity log of what bokeh serve is doing during the web view update? I have generated a log within my python code, and the ColumnSourceData is updated in about 0.25 sec. But then it takes another 19 sec for the view to update. Other objects in the view are non-responsive at this time, even the cross-hair in a plot will not update.
I’ll spend some time trying to come up with a simple code to demonstrate this… but my code is pretty massive and currently depends on database access, so this is no easy task to track down.

hello,see also my comments from 15. of December, just after release of 0.12.11.
I also stick to 0.12.10 since then, which is unfortunate because other bugs have been eliminated.
I was not able to isolate a self contained example from a rather large project.My comments were from looking at the js console, but it was a bit cryptic (to me). Like unnecessary refresh of non involved canvas when zooming.

Thanks Bryan. I’m working with a pretty massive Bokeh project, so it will take a lot of effort to track down some test code. Since 0.12.10 is working great, it hasn’t been a priority to investigate. Seems related to memory management though, from what I can tell my calculations using loaded data is the same… seems like web UI response issue.I’ll be sure to post on GitHub if I can definitely nail down the issue. Sorry I can’t clarify further right now.

Hi,There are certainly specific situations I have noticed, but nothing I’d describe as general. However, my day to day usage is not an all (or even most) platforms. But to investigate a performance problem we would really need:
- a GitHub issue
- with complete test case code
- platform/browser/version info
Thanks,

Has anyone else noticed a significant slow-down in GUI response starting with 0.12.11? 0.12.13 has the same issue.
In the meantime, I’ve just been sticking with 0.12.10 which works very smoothly.
For example, after I’ve defined a a query, and loaded some data… the tabs are not clickable for an extended period of time. I have a plot connected to a drop down that lets you pick your y-axis, what used to be a near instant update after dropdown selection takes 5 - 10 seconds now, or longer. I tried my code without tabs, same issue… in fact, I can’t even scroll the webpage for several seconds after data is loaded or after a dropdown selection.
Perhaps I could use some downsampling or something, but everything works great in 0.12.10… and I really don’t think I have that much data (no imaging data or anything).
