Maximum physical memory dedicated to SGX


It seems the maximum physical memory available to SGX in pretty much limited to 128MB. Is there a way to increase this limit? (Both Dell BIOS as well as Visual BIOS seem to have a 128MB limit, even though our Dell server has 32GB RAM.)

Having this low physical memory has a very high performance penalty. I have ported SQLite, and a 2GB database (doing near sequential access) has close to 162% overhead (including cost of ECalls and OCalls which are unavoidable).

Would like make a feature request to Intel to increase this limit to at least 4GB.
