Hi, 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.
