Slow loading #22

Closed yqu212 closed 3 years ago

yqu212 commented 3 years ago

The first url can load normally. If I use a new session, the other url will take more than one minute to load.

yqu212 commented 3 years ago

It's not related to Emacs GUI. I can use Emacs normally when the webkit is loading.

Do you also encounter this issue on other webktigtk based browsers like Epiphany?

yqu212 commented 3 years ago

I'll try it.

Another guy encountered the same issue. https://emacs-china.org/t/emacs-webkit-xwidget-webkit/15277/19

I have tried ehiphany. It can not start on wsl 1.

I also tried Midori. I encountered the same issue as webkit. New tab loads url very slow.

(midori:3604): GLib-GObject-WARNING **: 09:53:25.170: ../glib/gobject/gbinding.c:271: Unable to convert a value of type gpointer to a value of type CairoSurface Failed to get the memory usage

However, when I turn on Privacy Browsing, loading time become much less.

Loading baidu.com needs more than 4mins without Privacy Browsing. Loading baidu.com needs about 12s with Privacy Browsing.

Loading github.com needs more than 4mins without Privacy Browsing. Loading github.com needs about 47s with Privacy Browsing.

Midori's Privacy Browsing

Midori doesn't store any personal data: No history or web cookies are being saved. HTML5 storage, local database and application caches are disabled. Midori prevents websites from tracking the user: DNS prefetching is disabled.

I have confirmed that WebKit runs normally on wsl 2. This issue is related to wsl 1. Maybe switching to wsl 2 is a good idea.

akirakyle commented 3 years ago

I've never used wsl so I can't really comment on this issue further. From what I understand wsl 1 suffers many performance issues in translating linux syscalls, so it's likely inherent to that approach, which wsl 2's virtualization does not suffer.

yqu212 commented 3 years ago

I agree with you. Wsl 2 is the right way to use WebKit.
