[Qgis-user] postgis via VPN

[jcn]

 Hello,
I've a problem with postgis and qgis via VPN :

When editing the attribute table (TOC) of a database via VPN postgis:


In the POSTGRES logs : 


Dec 6 10:36:05 bdd postgres[18859]: [284-1] 2010-12-06 10:36:05 UTC LOG: duration: 0.317 ms statement: declare qgisfid0 binary cursor for select "gid","N_"::text,"N__DE_L_OB"::text,"DONN__ES_P"::text,"PNRUN_AUTR"::text,"NOM_D_COUV"::text,"NOM_S__OBS"::text,"DATE_D_OBS"::text,"DATE_IMPR_"::text,"HEURE_D_OB"::text,"UTMX"::text,"UTMY"::text,"COMMUNE"::text,"LIEU_DIT"::text,"N__SUR_LA_"::text,"SOLEIL__NU"::text,"MILIEU"::text,"ESP_CE"::text,"ADULTE_M_L"::text,"ADULTE_FEM"::text,"JUV_NILE"::text,"SEXE___GE_"::text,"REMARQUES_"::text,"R_DACTEUR_"::text,"VALIDEUR_S"::text,"VALIDEUR_2"::text from "public"."phelbor" where "gid"=35 Dec 6 10:36:05 bdd postgres[18859]: [285-1] 2010-12-06 10:36:05 UTC LOG: duration: 0.099 ms statement: fetch forward 1 from qgisfid0 Dec 6 10:36:05 bdd postgres[18859]: [286-1] 2010-12-06 10:36:05 UTC LOG: duration: 0.027 ms statement: CLOSE qgisfid0 Dec 6 10:36:05 bdd postgres[18859]: [287-1] 2010-12-06 10:36:05 UTC LOG: duration: 0.026 ms statement: COMMIT 
 
This represents a transaction and there is one for each line. That is very slow !.

=> If you add up all the times, we get 0491 ms for this, ie, it calculates two lines in one second
=> If the file has 120 lines ... it will take 1 min and 1200 lines for 10 minutes …
it's too long
 
If I use pgAdmin, it works well
