Memory manager - what?

Hi all,

What memory manager do you use in production servers that are to be heavily loaded on multiple threads?
FastMM is the bottleneck, ScaleMM is unstable (AV) SapMM is also unstable.
Are there other options worth considering?

FastMM4 gives the best performance/ resource ratio for a mORMot server.

The framework makes its best to minimize memory allocation.

But in my test environment with ScaleMM I get 3200 req/s and with FastMM only 2700 req/s. Difference is large.
RAM occupancy does not bother me, I care about performance.
Are there any other good memory managers?

I would rather optimize your server side code instead. Try to avoid memory allocation as much as possible.
