izardOn Tuesday night, I had a call that I need to urgently go to Israel. So at 11PM I bought a Turkish Airlines ticket, and at 6AM yesterday I was checking in to my flight at a Munich airport. At 4PM yesterday I was already at a customer office, and for 4 hours we were investigating a very strange performance issue, that has its roots very deep in a very low level details of CPU implementation. This is one of 2 strange low level issues I have on my active list. The first one is nearly solved thanks to very valuable help from ![[livejournal.com profile]](https://www.dreamwidth.org/img/external/lj-userinfo.gif)
shipilev and a linux kernel maintainer I should not name here.
By 8PM we've collected enough data to start reasoning, but I went to my hotel to check in and sleep over it. Today from 6AM till 8AM I plotted ~20 graphs in Excel that try to explain the data I got, and now I have 3 hypothesis to check today.
Writing this while having a breakfast outside a sunny cafe on Izhak Rabin square in Tel Aviv :) Really enjoying the weather after Munich.. Alas, flying back tomorrow at 5AM.
