@ -37,7 +37,7 @@ Notable aspects of the design include:
programs.
- __secure__: _mimalloc_ can be built in secure mode, adding guard pages,
randomized allocation, encrypted free lists, etc. to protect against various
heap vulnerabilities. The performance penalty is only around 3% on average
heap vulnerabilities. The performance penalty is usually around 10% on average
over our benchmarks.
- __first-class heaps__: efficiently create and use multiple heaps to allocate across different regions.
A heap can be destroyed at once instead of deallocating each object separately.

For best performance in C++ programs, it is also recommended to override the
global `new` and `delete` operators. For convience, mimalloc provides

To ensure the mimalloc DLL is loaded at run-time it is easiest to insert some
call to the mimalloc API in the `main` function, like `mi_version()`
(or use the `/INCLUDE:mi_version` switch on the linker). See the `mimalloc-override-test` project
for an example on how to use this.
for an example on how to use this. For best performance on Windows with C++, it
is highly recommended to also override the `new`/`delete` operations (as described
in the introduction).
The environment variable `MIMALLOC_DISABLE_REDIRECT=1` can be used to disable dynamic
overriding at run-time. Use `MIMALLOC_VERBOSE=1` to check if mimalloc was successfully redirected.
