This is extremely worrisome to me. The company that I work for has a bunch of 9i databases and a sandbox to test 10G. As we are primarily DW place, writes weren't tested yet. How many people here have implemented 10GR2 in production and is there a consensus about the problem with the speed of writing to the database? I'll search Metalink later.
