Hi, i have a performance problem while inserting data to sqlce.I'm reading string and making inserts to My tables.In LU_MAM table,i insert 1000 records withing 8 seconds.After Mam tables i make some inserts but my largest table is CR_MUS.When i want to insert record into CR_MUS,it takes too much time.CR_MUS has 2000 records and insert takes 35 seconds.What can be reason?I use same logic in my insert functions.Do u have any idea?I use VS 2008 sp1.

Dim reader As StringReader
reader = New StringReader(data)

cn = New SqlCeConnection(General.ConnString)
cn.Open()

If myTransfer.ClearTables(cn, cmd) = True Then
    progress = 0
     '------------------------------------------
cmd = New SqlServerCe.SqlCeCommand
Dim rs As SqlCeResultSet
cmd.Connection = cn
cmd.CommandType = CommandType.TableDirect
Dim rec As SqlCeUpdatableRecord

' name of table
