New performance tuning possibilities in syslog-ng On April’s fool’s day, I shared that <a href="https://peter.czanik.hu/posts/new-toy-1st-of-april-syslog-ng-performance-tests/" target="_top">syslog-ng can reach 7 million EPS</a>. This test lab result...

On #AprilFoolsDay, I shared that #syslog_ng can reach 7 million EPS. This test lab result was in part possible thanks to a few #performance enhancements coming to syslog-ng version 4.12.

How 7 million EPS is possible? Learn more at:

This weekend I was #hiking wearing my #IBMChampions t-shirt and a #RedHat backpack. This combination resulted in some very good discussions about #AI, #Linux and software #development :-)

This Monday I talked to a couple of friends about work while wearing my Genesi t-shirt. A #teacher going back to school after Spring break and an #IT guy explaining the nightmare of #RTO threat. I love coincidences :-) Why do I say that?

I love sweets but I'm also on a diet. Workaround: doing a #cardio #exercise before eating a #cake :-) In this case I ran up to the top of the Museum of Ethnography in Budapest.

Americans urged to reboot internet routers by NSA "Malicious actors may leverage your home network to access personal, private, and confidential information," the NSA said.

#NSA put together the best possible #advertisement for #Turris. They raise the awareness about #Russian military intelligence, and complain about lack of updates and default passwords in home routers.

My new toy: April 1 syslog-ng performance tests Almost 15 years ago, Balabit had a campaign, stating that syslog-ng could process 650k messages a second. Now I am happy to present 7 million EPS (events per second). Timing the announcement to April ...

Why "#syslog_ng can do 7 million EPS" was announced on #AprilFoolsDay? It is a completely valid result. However, it was measured not in a #production, but in a #laboratory environment.

So, it's an absolutely stunning result, just impossible in production.

The #Easter weekend is over. I had big plans about making my time useful with #LLL (life long learning): #ArtificialIntelligence, #coding, even a bit of #psychology.
Instead of that I went #biking, visited friends and family, a #BotanicalGarden, even a bit #gaming.
No regrets 🥰

My ultimate goal is to learn more about #ArtificialIntelligence in a #Linux environment, but the first thing I did after installation was trying #Steam and a couple of #games. Spoiler alert: installing #NeedForSpeed was smoother than on #Windows :-)
