When I load a raw log on Treeherder on windows atm, it seems to take about 8-10 seconds to load the page on Firefox, whereas on Chrome it's pretty much instant. I'm curious if anyone else sees this behavior on windows or another OS, or if it's just me. I've tried it on a couple of windows machines here. I hadn't encountered this kind of delay loading raw logs in the past. To reproduce: o load/re-load a link like this in Chrome, and in Firefox http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-central-linux/1419679350/mozilla-central-linux-bm72-build1-build125.txt.gz Expected: The load times might be roughly the same. Observed: Chrome is pretty much instant, maybe a second. Firefox is ~8sec to load and the browser is pretty much MIA while it's loading (though I guess that is single threading). My settings for both browsers are roughly defaults for each, give or take. Just in case there have been any changes in how the content is being hosted that impacts Firefox.
Curious if e10s helps or hurts perf here.
This is a bug in Firefox Core rather than treeherder, moving. Worth taking a look though :-)

I'm almost positive we have a similar bug open for when this happened on TBPL.
(In reply to Nathan Froyd [:froydnj] [:nfroyd] from comment #3) > I'm almost positive we have a similar bug open for when this happened on > TBPL. That's bug 762710 - about TBPL's parsed view, which stuffed the log content inside <pre>, whereas this is for the raw text files.
Well the HTML document which is created for raw text files is <html><head><link rel="alternate stylesheet" type="text/css" href="resource://gre-resources/plaintext.css" title="Wrap Long Lines"></head><body><pre> {the contents of the file} </pre></body></html>
Ha learn something every day :-) Happy for you to dupe/tweak as needed,.
