PostgreSQL
I am using Microsoft Visual FoxPro to connect VIA ODBC using both
a DSN connection and a DSNLess Connection. The DSNLess connection is
Waaaayyyyy... slower than the DSN connection and I am having a problem
trying to figure out what ODBC settings affect performance this much.
using DSN i can pull 4 fields x 953 rows in .266 seconds :)
however using a DSNLess connection the same query takes >179 seconds
(ouch =-O)
the DSN connection settings are all the default expet for
Database = systemdata
Server = 192.168.10.94
Username = postgres
I have been messing around with the DSNLess connection and have tried
changing quite a few of the setting but can't get the speed up, here are
some of the settings. As you can see they are pretty much the same.
lcSqlDriverName = "PostgreSQL "
lcSqlServerName ="192.168.10.94 "
lcSqlDatabase=" systemdata""
lcSqlUserName=" postgres"
lcSqlPassword=" "
lcSqlPort="5432 "
lcSqFetch="100"
lcSqOptimizer=" 1"
lcSqKsqo="1"
lcSqSqUniqueInd ex = "1"
lcSqBoolsAsChar = "1"
lcSqMaxVarcharS ize = "254"
lcSqMaxLongVarc harSize = "8190"
lcSqExtraSysTab lePrefixes = "dd_;"
lcSqProtocol = "6.4"
lcSqUpdatableCu rsors = "1"
lcSqLFConversio n = "1"
thanks......... .....
