Memory usage

Less threads

Vertex will use any core it detects(cgroup is supported), for example, if you have a 256-cores machine, then vertex will start at least 256 threads to handle async tasks. In your workload, you may waste 255 threads, so limit the worker threads is necessary.

So set the VERTEX_WORKER_THREADS environment or pass the proper value to -t or --threads.

VERTEX_WORKER_THREADS=2 vertex

vertex -t 2

Allocators

By default, vertex uses the system’s default allocator, which is good for most cases, but maybe not yours. Then users have to compile and test it.

Supported allocators:

jemalloc
snmalloc
mimalloc
scudo

compiling with command below:

cargo build --release --features jemalloc
