it looks like throughput reduced post deneb, which is curious, and I'd like to understand if we're missing anything when subscribed to all subnets in deneb world.

on holesky on an 8 cpu node i had to adjust a few parameters and increase the heap size significantly when enabling p2p-subscribe-all-subnets. was -Xmx16g before it got to 2% GC . and even then we were basically at 100% cpu.
--Xp2p-batch-verify-signatures-max-threads=8 \
--Xp2p-batch-verify-signatures-queue-capacity=30000
Need more investigation on a 16 cpu instance, but i think we'll need to specify some minimum specs for this mode.
