기존에 c2 + emmc 8g 조합으로 쓰다가 hc2를 들이고 우분투서버에서
유닉스벤치 돌려봤습니다.
Dhrystone 2, Double-Precision 점수만 괜찮고 나머지는 전부 c2 + emmc보다 떨어집니다.
HC2 + 샌디스크 익스트림u3 32g - System Benchmarks Index Score 708.6
c2 +emmc 8g - System Benchmarks Index Score 1033.1
sd, emmc의 차이때문에 약간 예상은 했었지만 생각보다 점수차가 크네요..
sd 속도나 호환성 문제 때문은 아닌거 같은데 한번 더 알아 봐야겠습니다.
