+### Set Up Ccache
+
+To speed up repeated compilations, we recommend that you install
+[ccache](https://ccache.dev), a tool that wraps your compiler so that it can
+cache build objects locally.
+
+#### Linux
+
+You can install it using the package manager, e.g. `sudo apt install ccache`
+(Ubuntu) or `sudo dnf install ccache` (RHEL).
+
+#### macOS
+
+You can install it using Homebrew, i.e. `brew install ccache`.
+
+#### Windows
+
+You can install it using Chocolatey, i.e. `choco install ccache`. If you already
+have Ccache installed, then `choco upgrade ccache` will update it to the latest
+version. However, if you see an error such as:
+
+```
+terminate called after throwing an instance of 'std::bad_alloc'

+```
+
+then please install a specific version of Ccache that we know works, via: `choco
+install ccache --version 4.11.3 --allow-downgrade`.

+ * a different allocator is in use, this function is a no-op and the report will

+ * @param journal Journal for diagnostic logging.
+ * @return Report containing before/after metrics and the trim result.
+ *
+ * @note If an alternative allocator (jemalloc/tcmalloc) is linked or preloaded,
+ *       calling glibc's malloc_trim may have no effect on the active heap. The
+ *       call is harmless but typically does not reclaim memory under those
+ *       allocators.
+ *
+ * @note Only memory served from glibc's sbrk/arena heaps is eligible for trim.
+ *       Large allocations satisfied via mmap are usually returned on free
+ *       independently of trimming.
+ *
+ * @note Intended for use after operations that free significant memory (e.g.,
+ *       cache sweeps, ledger cleanup, online delete). Consider rate limiting.
