Marking this as "fixed released" after the 2.6.39-rc5 kernel. It included a patch which included commit 57db4e8d73ef2b5e94a3f412108dff2576670a8a to convert eCryptfs to a writeback caching model.

The performance boost isn't as big as I'd hoped because we still have to flush the dirty data upon closing the file. This involves encrypting the data and writing it to the lower filesystem.

Due to the current eCryptfs architecture, there's simply not many more options to significantly increase the performance. Software encryption is expensive.
