SQL dotaz na kterem jsem to zkousel je:

tabulka mela 100000 radku /2 sloupce - id(int) a text(varchar(10))


Pro MySQL:

set objConn=server.CreateObject("ADODB.Connection")
objConn.Open
"server=127.0.0.1;db=sqltest;driver=MySQL;uid=iismysql;pwd=123456;"

For  i = 1 To 1000

set objRst=server.CreateObject("ADODB.RecordSet")
with objRst
   .Source = "SELECT * FROM test"
  .ActiveConnection = objConn
   .CursorType = adOpenForwardOnly
   .LockType = adLockReadOnly
   .PageSize = 10
   .Open
 end with

Next

Doba:  7.45 min


********

Pro MSSQL:


set objConn=server.CreateObject("ADODB.Connection")
objConn.Open
"Provider=sqloledb;Network=DBMSSOCN;Server=localhost;Database=test;UID=iisus
er;PWD=123456;"

For  i = 1 To 1000

set objRst=server.CreateObject("ADODB.RecordSet")
with objRst
   .Source = "SELECT * FROM test"
  .ActiveConnection = objConn
   .CursorType = adOpenForwardOnly
   .LockType = adLockReadOnly
   .PageSize = 10
   .Open
 end with

Next


Doba:  2.53 min.
