For comparison, only 10% fail this metric for 1MB blocks. Note how due to bandwidth being generally asymetric your findings are probably optimistic - you've measured download capacity. On top of that upload is further reduced by the fact that multiple peers at once need to be sent blocks for reliability. Secondly you're measuring a network that isn't under attack - we need significant additional margin to resist attack as performance is consensus-critical. -----BEGIN PGP SIGNATURE----- iQE9BAEBCAAnIBxQZXRlciBUb2RkIDxwZXRlQHBldGVydG9kZC5vcmc+BQJVsRCj AAoJEMCF8hzn9Lnc47AIAIQbznavjd2Rbqxeq5a3GLqeYoI4BZIQYqfWky+6OQtq yGRKaqPtGuES5y9L0k7efivT385mOl87PWnWMy61xxZ9FJgoS+YHkEx8K4tfgfA2 yLOKzeFSar2ROCcjHYyPWa2XXjRbNmiLzfNuQyIBArg/Ch9//iXUUM+GG0mChF5k nUxLstXgXDNh5H8xkHeLi4lEbt9HFiwcZnT1Tzeo2dvVTujrtyNb/zEhNZScMXDc UOlT8rBLxzHlytKdXt1GNKIq0feTRJNbreBh7/EB4nYTT54CItaaVXul0LdHd5/2 kgKtdbUdeyaRUKrKcvxiuIwclyoOuRQp0DZThsB262o= =tBUM -----END PGP SIGNATURE----- _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
