Cristian Staretu 61ccc1f05f archive/tar: reuse temporary buffer in readHeader ... A temporary 512 bytes buffer is allocated for every call to readHeader. This buffer isn't returned to the caller and it could be reused to lower the number of memory allocations. This CL improves it by using a pool and zeroing out the buffer before putting it back into the pool. benchmark old ns/op new ns/op delta BenchmarkListFiles100k 545249903 538832687 -1.18% benchmark old allocs new allocs delta BenchmarkListFiles100k 2105167 2005692 -4.73% benchmark old bytes new bytes delta BenchmarkListFiles100k 105903472 54831527 -48.22% This improvement is very important if your code has to deal with a lot of tarballs which contain a lot of files.
