(https://github.com/bitcoin/bitcoin/pull/27626#discussion_r1192406738)
This "warmup" should really only be an issue after we've seen new blocks from 3+ peers since we don't persist hb peers across restarts and we have to wait for `MaybeSetPeerAsAnnouncingHeaderAndIDs` to be called on multiple unique peers. I now suspect the warmup period handles itself? My logs show 4+ blocks per node with only one partial block.

ACK de202f860b3f79774d5235dec59a140fa5c82fa7, tested on Ubutnu 23.04.

The test is deadlocked with the second commit dropped as well.

So far my results with `MALLOC_ARENA_MAX=1` seem to be good, I've been comfortably under 2GB RAM every time I've checked. I added it as an env var in my systemd configuration which I copied and modified from the one in this repo, I figure it ought to have that env var as well. I'll open a PR to add it.

This adds the `MALLOC_ARENA_MAX=1` environment variable as suggested in https://github.com/bitcoin/bitcoin/blob/master/doc/reduce-memory.md#linux-specific to the systemd service file definition.

Without this env var, memory usage can grow significantly especially when `rpcthreads` is increased above its default value.

Closes #24542.

I think setting this to 1 will give significantly worse performance for most users though?

Seems like it would be better to add it to the documentation if anything...

(https://github.com/bitcoin/bitcoin/pull/27596#issuecomment-1545856135)
I've done a number of runs here with some combination of indexing and pruning, and I think this is in about as good a shape as it can be, with the following caveat:

When using assumeutxo with pruning and indexing, the snapshot chainstate cannot be pruned because of how we handle indexing during bg sync. Since the snapshot chainstate isn't indexed until after the background sync completes (in order to avoid out-of-order indexation), we aren't able to prune the snapshot chainstate based upon th

Thank you for looking -- "to" (as in "toward") is correct here.

> Any reason not to send `TX` directly and avoid the `INV`, like below?

It has been suggested to stop processing unrequested TXs messages, see #21224. While that didn't make it, the idea is still floating around. If bitcoin core itself started relying on unrequested msgs being processed, that would probably kill it once for all.
Maybe that's ok, but we should make sure that there aren't alternative clients that would ignore unrequested TXs.

Looks like I goofed somehow when editing my branch to remove some whitespace and that resulted in closing this PR, that's what I get for creating the original commit in the github.com text editor. Reopened in #27642.
