Hi,
How fast to you get the results of your 300 queries on the LAN?
Have you maybe tried sniffing the network, for example with tcpdump?

Objet : [ODBC] Slow query over ADSL Line
Hello,
I'm using psql ODBC driver with ADO in a visual basic 6 application, and I
have some speed issues when I connect using an adsl line (8M down/1M up) (it
works perfectly well using an ethernet 100Mbps LAN).
The application sends about 300 queries to server, and it takes 150 seconds
to fetch the results of all queries. I have also tested some of the queries
with pgAdmin, and it takes about 1.5s/2s for each query.
The queries are all in the same simple form : "select
myfield1,myfield2,myfield3[...] from table where id=myid", and they send
back only 40/50 rows max.
I have no debug option enabled, and there is no "blob" object in my
database.
I use the following options with ADO recordset :
Dim rec as ADODB.Recordset
set rec=New ADODB.Recordset
rec.open myquery, myDbConn, adOpenStatic, adLockReadOnly, adCmdText
Does the slowness is due to ADO or ODBC ?
Is there a simple way to speed up the result fetch ?
Thanks in advance,
Regards
Thomas Chabaud
