Tezos-node synchronisation issues

Hi There,

I have machines on mainnet and carthagenet, as well.
I have used the tezos-node config init command to get a list of bootstrap-peers but when I run it, it is super slow to sync and quite often it says

p2p.maintenance: Too few connections (n)

Unfortunately I need to run it as --history-mode=archive.
Currently I have this list for mainnet:

  "p2p": {
    "bootstrap-peers": [
      "boot.tzbeta.net",
      "dubnodes.tzbeta.net:9732",
      "franodes.tzbeta.net:9732",
      "sinnodes.tzbeta.net:9732",
      "nrtnodes.tzbeta.net:9732",
      "pdxnodes.tzbeta.net:9732"
    ],

and this for testnet:

  "p2p": {
    "bootstrap-peers": [
      "34.76.169.218",
      "34.90.24.160",
      "carthagenet.kaml.fr",
      "104.248.136.94",
      "carthagenet.smartpy.io:9732"
    ],

Does anyone know more peers I could connect to? Or a secret trick to speed up tezos-node reconstruct?
