Poor performance of File Caching caused by PartOnFile
-----------------------------------------------------
Key: AXIS2-2516
URL: https://issues.apache.org/jira/browse/AXIS2-2516
Project: Axis 2.0 (Axis2)
Issue Type: Improvement
Components: om
Reporter: Liyu Yi
I noticed that the performance of "File Caching" is not great, and I believe it
is due to the implementation of the constructor of
"org.apache.axiom.attachments.PartOnFile" which reads and writes the inputSteam
byte-by-byte (see the snippets below). Can we simply apply some buffering to
improve it?
public PartOnFile(PushbackFilePartInputStream inStream, String repoDir) {
...
cacheFile = File.createTempFile("Axis2", ".att",
repoDirFile);
FileOutputStream fileOutStream = new FileOutputStream(cacheFile);
int value;
value = parseTheHeaders(inStream);
fileOutStream.write(value);
while (!inStream.getBoundaryStatus()) {
value = inStream.read();
if (!inStream.getBoundaryStatus()) {
fileOutStream.write(value);
}
}
fileOutStream.flush();
fileOutStream.close();
} catch (IOException e) {
throw new OMException("Error creating temporary File.", e);
}
}
