上传文件时需要插入大量数据：最佳解决方案？

Question

I found a solution at my problem, but my knowledge limits me to see other solutions;

Context: we would upload a Perfmon file to the web application, and store all the values in database. the file has this csv structure:

---

time, counter1, counter2, counter3(process1), ...

0:00, x, y, z,...

0:30, ...

---

(x, y and z are values obviously)

As an example, a 3 months worth of Perfmon would generate more or less 2M data.

My solution: on file uploading, some logic would read and transform the file with the following structure:

---

time, counter, process, value

0:00, counter1,, x

0:00, counter2,, y

0:00, counter3,process1,z

0:30, ...

---

Saving this file, my database can then do a bulk insert knowing the path.

I can't think of other solution that wouldn't require tons of transactions, or being more optimized. Though this solution can have some limitation as the database server needs to have the right permission over the storage server.

Open to hear your thoughts, Cheers!
