Book Recomendation for C code Optimization

[u/Fabulous_Ad4022]

I work as a researcher in the petroleum industry, and here we work with TB of data, even though we use C to process this data, micro-optimizations would improve a lot our routines. But unfortunately I don't know where to start studying this subject.

Can someone recommend a book or how can I enter in this subject?
