I tried the giantnode script, which crashed at ~660k payments/invoices because my /tmp was only 32GB and i think the log files were a big part of it.
Anyways i stopped all 3 nodes and started them again and noticed that l1 and l2 started very fast, as expected, but l3 takes ~1.5 hours on a ryzen 5900x 64GB ram, nvme ssd machine to start up.
