optimising filesystem for many small files

System : Fedora 11 x86_64
Current Filesystem: 150G ext4 (formatted with "-T small" option)
Number of files: 50 Million, 1 to 30K png images

We are generating these files using a python programme and getting very slow
IO performance. While generation there in only write, no read. After
generation there is heavy read and no write.

I am looking for best practices/recommendation to get a better performance.

Any suggestions of the above are greatly appreciated.
