Re: [birt-dev]CheckIn: optimize the performance of archive file

[Sunitha Kambhampati <ksunithaghm@xxxxxxxxx>]

Hi,

I saw this checkin mail and it got my attention as I am interested in 
performance of BIRT also & I'd  like to contribute to improving 
performance.

While fixing this issue, are there any other known performance issues 
that you may have found, that might be good to fix. If so, can you 
please point it. I'd be interested in looking at it and maybe it will 
also encourage others in the community who may want to look into it.

Thanks very much.
Sunitha.
