## Proposed changes When compiling Doris, the default page size used by Jemalloc is 4K. If used in a system with a page size of 64K, an error message of `unsupported system page size` will be reported. It needs to be compiled with `PAGE_SIZE=64K ./build.sh` Jemalloc compiled on a system with page size 4K can only run on a system with the same page size 4K. If it is run on a system with page size > 4K, an error will be reported. But Jemalloc compiled on a system with page size 64K can run on a system with page size < 64K, but this will waste more memory. Jemalloc does not support dynamic adaptation to the page size of the system. The reason is that jemalloc will perform some optimizations based on the page size when compiling. ## Further comments If this is a relatively large or complex change, kick off the discussion at [[email protected]](mailto:[email protected]) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
