In some "Small and Medium" applications with relatively high concurrency, if a large amount of data is inserted in the short term, using MSMQ is a good choice (petshop is doing this ), do you want to know how many records can be sent in one second by MSMQ?

The result of running on my IBM t60 is about 2500 records per second (that is to say, 2500 orders can be smoothly placed in one second, and it should be enough in Small and Medium Sized Shopping Systems)
