[Links of the Day] - 18/01/2018 : Stellar Cryptocurrency Consensus protocol, Optimizing linux server for high throughput and low latency, performance impact of meltdown patch on HPC Filesystem

  • Stellar Consensus Protocol : from ripple for to full-blown rewrite. Stellar looks like an impressive protocol addressing many of the shortcoming and risk of Ripple. Also, the authors seem to be smart enough to avoid jumping to fast onto the smart contract aspect as it is a really tough nut to crack. Maybe, with all the mayhem surrounding cryptocurrency, the stellar approach seems to be rather measured. Worth keeping an eye on. 
  • Optimizing web servers for high throughput and low latency : very good post on how to optimise your Linux system. A lot of it has already described many times, but it is never a bad thing to repeat them.
  • The performance impact of Meltdown patches on HPC FS (Lustre) : no surprise here, IO intensive applications are the one the most heavily impacted. However, I wasn't expecting 40% performance penalty and up to 45% for large folders.
