etcd on arm

[jaro1122334455]

Hello,
I want to use etcd on arm64 (need to save data from xml to db on embedded device). I tested it at first on x86 and everything works fine, it saves data in ms then I use buildroot to add etc to board (try on raspberry pi 4 and imx 93 64bit builds) and the performance was terrible. It saves data but in 40s so I try use directory in /tmp to save data on ram, this improved situation but not enough (14s).
I would like to ask if using etcd on arm is not optimized or what is the problem.
