Android File IO Performance Test

並沒有參考過 Linux open community tool 的 algorithm

這是下一步要改進的

目前針對以下幾個項目，然後用各種不同的 Java IO 方式來進行測試

l   Src / Dst path [option]

l   File size [option]

l   Test cases

n   Sequential R/W (Postpone)

n   Random R/W (Postpone)

n   Creating (Low IO / High IO / New IO with buffer size, file size and algorithm)

u  Create many small files

u  Create large file

n   Copying (Low IO / High IO / New IO with buffer size, file size and algorithm)

u  Copy many small files

u  Copy large file

n   Deleting

u  Delete many small files

n   File compression / decompression

n   File encryption / Decryption

Test scenario: (Algorithm, BufferedReader, BufferedWriter, read / write by buffer)

         //createNative1(dstFlash, size);

        createNative2(dstFlash, size);

        createBuffered(dstFlash, size);

        createNIO(dstFlash, size);

        createRandom(dstFlash, size);                             

        //nativeStream1(srcFlash, dstFlash, size);

        nativeStream2(srcFlash, dstFlash, size);

        //nativeReader(srcFlash, dstFlash, size);                             

        //bufferedStream1(srcFlash, dstFlash, size);

        bufferedStream2(srcFlash, dstFlash, size);

        //bufferedReader1(srcFlash, dstFlash, size);

        //bufferedReader2(srcFlash, dstFlash, size);

        customBufferStream1(srcFlash, dstFlash, size);

        customBufferStream2(srcFlash, dstFlash, size);

        //customBufferReader1(srcFlash, dstFlash, size);

        //customBufferReader2(srcFlash, dstFlash, size);                               

        newIOBuffer(srcFlash, dstFlash, size);                         

        bySystemCmd(srcFlash, dstFlash, size);                               

        // copySmallFiles(flashPath, flashPath);

        // customBufferBufferedStream(srcFlash, dstFlash);

        // customBufferBufferedReader(srcFlash, dstFlash);

        // appliedCompression(srcFlash, dstFlash, size);

        // appliedCaching(srcFlash, dstFlash, size);
