Hello !
I am working on a comparison between Rust and C and I would like to compare the memory usage of both algorithms. I think that Rust consumes less memory than C because of the use of iterators, but my question is, which tool is useful to calculate the memory usage ?
Thank you !!
What OS?
On Linux !
If you compile the executable with cargo build --release, you will find the binary at ./target/release/your_package_name. You can then try
/usr/bin/time -v ./target/release/your_package_name
Then look for the line with "Maximum resident set size".
See this question for more info.
Thanks ! And this works with parallel programs or only with serial programs ?
Should work in parallel too.
If you want to know byte-exact amount of memory allocated by Rust itself, you can instrument Rust's memory allocator. For example, there's cap. But for comparison with C, an external measurement will be more fair.
