MultipartPostMethod takes long time to execute

Hi,

I use MultipartPostMethod to do upload, but I found that it takes 3-4
seconds to execute even for a very small file (<1KB).
int status = httpClient.executeMethod(filePost);

Does anyone have the same problem? How to improve the speed?


I also found that the HttpClient fragment the post method to many
packets, each with a few adte byte in content. Can we change it?

Thanks,

Martin Chan

Thanks Ortwin, I added "filePost.setUseExpectHeader(false);" and it works.

This can have two reasons:

- When TCP_NODELAY is set and the data is delivered to slow, the data 
may fragment more than with TCP_NODELAY disabled.

- There can be a wait time involved due to 100-Continue handshake. Try 
and disable 100-Continue handshake.
