[yast-devel] Webyast - speed up
  • From: Josef Reidinger <jreidinger@xxxxxxx>
  • Date: Wed, 30 Jun 2010 15:36:59 +0200
  • Message-id: <201006301537.00187.jreidinger@xxxxxxx>
Hi, I with miso result that parsing doesn't slow down webyast I check what take
so much time and I found that we have increadible amount of unnecessary
communication in webyast.
So I propose these two changes which should speed up webyast:

in webclient store together with site, login and auth_token also resources for
such site and permission for site and user.

advantages:
- reduce communication between webclient and rest-service so It should speed up
webyast
- client side caching ( now permissions and resources is cached at
rest-service) has advantage that it doesn't require communication and parsing
of result

disadvantage:
- permissions which affect which form is disabled is refreshed only during
login (of course it doesn't affect permission checking in rest-service). So if
user change permission for itself, then he must relogin to affect forms.

I plan to experimental implementation in own branch, so if you have any
comments and ideas I welcome it.

Josef


JFYI: communication for one show of time page (all request is quite quick, but
each of them need some communication overload):
