Hi,
We had the same problem in my project. Two different approaches were taken:
1. We have many OL layers where the same geoserver featureType can be
referred by more than one OL layers (but with different SLD and CQL_FILTER),
so we aggregate the WMS requests to the same geoserver featureType this
reduced the number of requests in 60%.
2. Our platform is accessed in a closed environment with IE, so it was
possible to recommend the registry update.
But still
not a Geoserver issue J
Cheers,
Pedro

shows 10+ seconds in "blocking" time
Hello Pedro,
This is an interesting suggestion. This site is used by many people.
Would you recommend trying to get all users of this site to up their max
connections parameters?
Thanks,
Jim

shows 10+ seconds in "blocking" time
Hi Jim,
This isnt a Geoserver issue. According to this
(http://www.softwareishard.com/blog/firebug/firebug-net-panel-timings/)
Blocking: Elapsed time spent in a browser queue waiting for a network
connection. Displayed only in the case where this situation happens
Until one of the available connections are released the requests will be
waiting. So if GS isn´t responding in a fashionable way to the WMS requests
your user experience will be kinda bad.
You can increase the value of Max TCP Connections per server:
Firefox (default=16): about:config »
network.http.max-connections-per-server;
IE (default=2): create a registry file (.reg) and run it
Example
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet
Settings]
"MaxConnectionsPer1_0Server"=dword:0000002
"MaxConnectionsPerServer"=dword:0000002
(where 0000002 should be changed to the value you prefer)
Keep in mind that this kind of settings are valid for all the connections
your browser establish.
Cheers,
Pedro Mendes

10+ seconds in "blocking" time
Hi,
I am looking into to performance tuning our Geoserver production
environment.
I have attached a firebug profile for the site. On page 5 of 14, there
is a large jump in blocking time reported by firebug when doing wms GET
requests.
I am curious as to why this jump is occurring. Has anybody else
encountered this issue? Does anybody know what can be done about this?
Thanks,
Jim
