I've been working on a project of mine which makes web requests via libCURL, and the number of memory allocations OpenSSL makes for a single TLS connection is astonishing - running it through `heaptrack` was a real eye-opener.

Discussion I found about other people mentioning it:

In some cases (not all) for my workflows perf record traces show the allocation / deallocation overhead is quite significant, especially in a multi-threaded setup, where contention against the system allocator starts to become a problem in some situations.
