good to know about the latest version. i'm also on chrome, on a nexus 5. this slow loading experience has been the case since rolling out lines. i found a few posts here on mobile slowness, and a whole bunch more at discourse itself, but no concrete solutions or explanations. the few exceptionally unhelpful posts, by discourse upstream, that i've found are concerned with old, unsupported android versions and VMs.
the most useful, recent pointers indicate the problems may lie mostly with the emberJS framework that discourse uses, but there's still no workaround. switching to iOS, as upstream discourse tells everyone to do, is not really a solution. at this point, i'm stumped, but still continuing to investigate.
