Create a simple cache in C# .NET

Here is a little sample of code I have written to simulate a cache, wich write the data every second on disk in the background in a dedicted thread.

Using this class Engine, you can write data to the internal dictionary and keep it safe because the database is written to disk… I do not have handled the reload of the data in the ctor… Here the client program who write any number of values you want:

If I run the console application using different values, here is the result:

D:\Dev\MyCache\ConsoleApp1\bin\Debug>ConsoleApp1.exe 10
Count: 10
Time elapsed set: 0 ms
Time elapsed get: 0 ms
Writing DB…
Writing DB OK

D:\Dev\MyCache\ConsoleApp1\bin\Debug>ConsoleApp1.exe 100
Count: 100
Time elapsed set: 0 ms
Time elapsed get: 0 ms
Writing DB…
Writing DB OK

D:\Dev\MyCache\ConsoleApp1\bin\Debug>ConsoleApp1.exe 1000
Count: 1000
Time elapsed set: 1 ms
Time elapsed get: 1 ms
Writing DB…
Writing DB OK

D:\Dev\MyCache\ConsoleApp1\bin\Debug>ConsoleApp1.exe 10000
Count: 10000
Time elapsed set: 7 ms
Time elapsed get: 13 ms
Writing DB…
Writing DB OK

D:\Dev\MyCache\ConsoleApp1\bin\Debug>ConsoleApp1.exe 100000
Count: 100000
Time elapsed set: 98 ms
Time elapsed get: 140 ms
Writing DB…
Writing DB OK

D:\Dev\MyCache\ConsoleApp1\bin\Debug>ConsoleApp1.exe 1000000
Count: 1000000

Writing DB OK
Time elapsed set: 3656 ms
Time elapsed get: 4023 ms
