Slowness when loading code in Pharo 7?
Hi, Are there any know slowdowns when loading code in Pharo 7? Usually on my machine (Mac - HighSierra) loading GToolkit in a Pharo 6.1 images takes around 9 minutes. In the latest Pharo 7 it takes 20 minutes. On two other newer laptops running Mac results are similar (15 minutes on Pharo 7 64it, and 7 minutes on Pharo 6.1 64bit). We have the impression that most of the times, the regression happens because of reading sources file. And the sources files are read because of checking Epicea method changes. We have not done a deep research on it, just whenever we do CMD+. it stops in that stage. Cheers, Andrei

I believe that actually loading source code from somewhere, compiling and installing it are not that slow, it is everything that happens around that, source code and change logging, tool notification, etc, .. For accepting one method change, that is all good, but not when loading massive amounts of code. We had discussions about this before, I think this is a really important issue. Sven
Hi Andrei. You can evaluate "EpMonitor current disable" before loading to compare times. El mar., 2 de oct. de 2018 a la(s) 11:18, Andrei Chis (chisvasileandrei@gmail.com) escribió:

Hi Martin, By disabling EpMonitor, the slowdown disappears. EpMonitor current disable. [ Metacello new baseline: 'GToolkit'; repository: 'github://feenkcom/gtoolkit/src'; load. ] timeToRun "0:00:08:03.504â Cheers, Juraj
