.net - How fast is SQLite compared to Microsoft Access MDB?

Question

Currently I'm thinking about replacing the usage of Microsoft Jet MDB databases on a single-user .NET C# Windows Forms application by a SQlite database.

My goal is to lower installation requirements like the Jet drivers and some nasty errors when the Jet installation got corrupted (we have customers every now and then reporting those errors).

My question regarding performance is:

Are there any performance benchmarks out there comparing MDB and SQLite on a rather small sets of data?

Or are there any developers who already did this step and can tell some stories from their own experiences?

(I am googling for hours now without success)

Update

Although the database does not contain that many records and tables, I think performance is still an issue, since the data is being accessed quite often.

The application is a so called "Desktop CMS system" that renders HTML pages; during the rendering, quite a lot of data is being accessed and lots of SQL queries are being executed.

Update 2

Just found this documentation which indicates some speed comparisons, unfortunately not with MDB, as far as I can see.

Update 3

As of request, some figures:

• approx. 30 tables in the database.
• Most tables with way below 100 records.
• approx. 5 tables with usually a few 100 up to a few thousand records.
• A large MDB file would be around 60 MB.

Update 4

Just to rephrase: I am not having any performance issues with the current MDB implementation. I am asking this question to get a feeling whether the performance would be equal (or better) when using SQLite instead of MDB.

Answer 1

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.
