Dear Derick and team,

Thank you for the award—I am humbled by the recognition. This was an 
interesting rabbit hole to dive into and I was happy to see the optimisation 
deliver such tangible results after the initial investigation was concluded. 
Looking forward to see the next interesting Perf Hero story!

Best regards,
Máté Szabó (he/him/his)
Staff Software Engineer
