cognos slow with second dispatcher

[chilonnb]

hello,

i'm using distributed architecture for cognos 10.2.1

server 1 : Cognos Web + Gateway (dispatcher for gateway : dispatcher server 3 then dispatcher server 4)
server 2 : cognos web + gateway (dispatcher for gateway : dispatcher server 4 then dispatcher server 3)


server 3: cognos BI App + CM (CM1)
server 4 : cognos BI App + CM (CM1)

SGBD CM1 = database sql server 2012


dispatcher server 3: http://server3:9300/p2pd/servlet/dispatch/ext
dispatcher server 4:  http://server4:9300/p2pd/servlet/dispatch/ext


when server 3 and 4 is ok, access on web servers (portal) is ok

when server 4 fail, the cognos web access (portal) from server1 is OK, but the cognos web access (portal) from server2 is very slow,

when server 3 fail, the cognos web access (portal) from server2 is OK, but the cognos web access (portal) from server1 is very slow,

any ideas please,

thanks,
