P2Pool v4.18 released with support for 100K Stratum connections

SChernykh¹ has released P2Pool² version 4.18³ with support for up to 100,000 Stratum connections (a considerable upgrade from only 10K in previous versions)⁴:

100,000 simulated mining rigs [..] More than 3,000 messages per second on Stratum, each message gets replied in less than 0.1 ms - 99th percentile (p99) = 0.1 ms. [..] Previous P2Pool versions were struggling [..] I found the source of performance issues and fixed it.

Changes overview

* [Feat] Optimized Stratum server performance
* [Feat] Crypto cache: 10% less CPU time spent on block verification
* [Fix] Don't use SOCKS5 proxy to connect to a private/LAN hosted Monero node
* [Fix] Stratum: fixed a potential double free when shutting down
* [Fix] Stratum: fixed inconsistent accounting if submit_sidechain_block fails
* [Fix] Fixed a crash when initializing dataset on 256 (or more) thread systems

The full list of changes since v4.11 is available on Github⁵.

Before using the software, you should verify the SHA256 sums with SChernykh’s GPG key⁶.

The README⁷ has valuable information about features, defaults, how pool shares work, build instructions and a short mining guide. If you need assistance, read the FAQ⁸ and join the project’s IRC channels⁹.

Note that it is strongly recommended to synchronize your system clock before you start mining; create a new wallet and don’t use it for anything else but mining for privacy reasons - all wallet addresses are public on P2Pool!
