How fast is SQLite compared to Microsoft Access MDB?

In case you decide to do your own benchmark testing, I offer this procedure to export your Jet tables to CSV files. Then you can import them into your SQLite database.

Public Sub DumpTablesAsCsv()
    Dim db As DAO.Database
    Dim tdf As DAO.TableDef
    Dim strCsvFile As String
    Dim strFolder As String
    Dim strTable As String

    strFolder = CurrentProject.Path & Chr(92)
    Set db = CurrentDb
    For Each tdf In db.TableDefs
        strTable = tdf.Name
        If Not (strTable Like "MSys*" Or strTable Like "~*") Then
            strCsvFile = strFolder & strTable & ".csv"
            DoCmd.TransferText acExportDelim, , strTable, _
                strCsvFile, HasFieldNames:=True
        End If
    Next tdf
    Set tdf = Nothing
    Set db = Nothing
End Sub

More than 4 years later, I actually did a small (probably somewhat naive) performance comparison test between MDB and SQLite.

I've also added more databases.

Datebases I've tested

  • SQL Server Express 2014 on the same local PC and local SSD drive as the test application.
  • SQL Server Express 2014 on a server in a gigabit LAN.
  • SQL Server Compact (CE) on the same local PC and local SSD drive as the test application.
  • Microsoft Access MDB/Jet on the same local PC and local SSD drive as the test application.
  • Microsoft SQLite on the same local PC and local SSD drive as the test application.
  • Microsoft VistaDB 5 on the same local PC and local SSD drive as the test application.

Since some databases do not support connection pooling, I've done two tests:

  1. One test with closing the connection as soon as possible through a using block.
  2. Another test with an always open connection to each database for the entire application lifetime

Test results when closing the connections immediately

  • SQL Express running locally was the fastest.
  • SQL Express on our local network was at second position.
  • SQL Compact Edition (CE) was much faster than SQLite and Jet/MDB.
  • Jet/MDB was a little bit faster than SQLite and much slower than SQL CE.
  • SQLite was a little bit slower than Jet/MDB.
  • VistaDB 5 was the slowest database in my test.

Test results when keeping the connections open

The results are rather similar to the results when closing a connection immediately.

Relatively to each other, the order from the fastest to the slowest did not change. Some databases with no actual connection pooling improved their absolute performance quite a bit.

  • SQL Express running locally was the fastest.
  • SQL Express on our local network was at second position.
  • SQL Compact Edition (CE) was much faster than SQLite and Jet/MDB.
  • Jet/MDB was a little bit faster than SQLite and much slower than SQL CE.
  • SQLite was a little bit slower than Jet/MDB.
  • VistaDB 5 was the slowest database in my test.

- SQLite            : 00:00:18.6504260
- VistaDB           : 00:02:26.0513056

Update 1, April 2019

I did some tests comparing Microsoft Access MDB to LiteDB, an embedded database for .NET.

So again, some rather naive comparison, but I still wanted to get a feeling.

This code does 1000 reads and writes and resulted in these values:

Access             of 1000 WRITE iterations took 00:00:39.6488351.
LiteDB             of 1000 WRITE iterations took 00:00:01.6596646.
LiteDB (in-memory) of 1000 WRITE iterations took 00:00:00.1617220.
Access             of 1000 READ  iterations took 00:00:48.8517302.
LiteDB             of 1000 READ  iterations took 00:00:00.0082401.
LiteDB (in-memory) of 1000 READ  iterations took 00:00:00.0097933.

So in my scenario, LiteDB was much faster than Access.

Update 2, April 2019

I've also ran my original code against VistaDB 6 Beta 1 in comparison to VistaDB 5.

I've got very similar speed results. The Beta of VistaDB 6 was slightly slower compared to VistaDB 5, most likely because it was a debug build.

As a conclusion, I see no significant performance improvements in my scenario between VistaDB 5 and VistaDB 6 Beta 1. I will have to try again with the final version of VistaDB 6.
