  • J2ME Phone Memory Test
    Computer/J2ME for GSM 2005. 1. 12. 23:01

     

    Nokia Series 40 platform 메모리 최적화 과정중에 발견한 결과들

     

    1. Just Creating InputStream of size 9215, 5722
    7210
    200412 - 191180 = 9232 bytes(9215 bytes)
    200412 - 194672 = 5740 bytes(5722 bytes)

    6230
    7647680 - 7638444 = 9236 bytes(9215 bytes)
    7647680 - 7641936 = 5744 bytes(5722 bytes)

    ... InputStream object size is as large as the file size.

     

    2. Creating InputStream & Image of size 442
    7210 : 1968  bytes
    6230 : 972 bytes
    ... 7210 may have stupid implementation
     
    3. Creating Image by createImage of size 442
    7210 : 1508 bytes
    6230 : 512 bytes

     

    4. Comparision between 2 & 3
    1968 - 1508 = 460 ( ~ 442)
    972 - 512 = 460 ( ~ 442)
    ... this result confirms 1.
