[jbosstools-issues] [JBoss JIRA] (JBIDE-20362) Extracting of a download runtime is slow on Mac

[Rob Stryker (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-20362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13279888#comment-13279888 ] 

Rob Stryker commented on JBIDE-20362:
-------------------------------------

Yes, there's a clear difference in how they're being called. 

The one that's been fixed uses ProgressMonitorDialog, a class in the org.eclipse.jface package.   The ProgressMonitorDialog makes use of an AccumulatingProgressMonitor, which is also private to jface. 

However, when launched via preferences, we're actually seeing ProgressMonitorFocusJobDialog

ProgressMonitorFocusJobDialog cannot use the AccumulatingProgressMonitor because it is private to jface. So instead it bombards swt with events.

> While playing with the Download runtime fuctionality, I noticed that once a runtime (e.g. EAP 6.2) is downloaded, the extraction takes very long. I think it used to be fast and the extraction was done without any progress reporting. But now it seems that every subdirectory in the archive is being printed out which slows it down.
> This extraction process took 1 min 23 sec for EAP 6.2 and I have an SSD. On a command line, this would take a few seconds.
> I think the solution may be to simply show "Extracting" without printing out each file/directory that is being extracted.
> (Furthermore, the progress bar does not reflect the progress - it seems there is still only perhaps 5 % done and then it's suddenly over.)
> I can record a screencast if you like, but I think this should be easy to replicate.
