Re: [birt-dev]CheckIn: optimize the performance of archive file
|
Thanks for the explanation and for working on this performance
improvement. Yes - I agree reducing the I/O of report generation
should help performance.
Are you looking at the next step of replacing the old archive format. Is
there a specific bugzilla entry for this?
regards,
Sunitha.

The archive file is a new format of report document. In BIRT 2.2, we
prepare to use this format to replace the old archive format.
The old archive uses a temporary folder to store streams created in
generation. After finishing the report document, it archives the files
to a single file.
The new format will write the streams directly into the single file.
So it will reduce the IO of report generation about 50%.
Currently, there is no performance increase after this check-in as BIRT
doesn't use it to replace the old archive. It will be implemented later.
