MultiRecordEngine - long time to write records (flush)

[mdrewanz]

Hi,
We are using FileHelpers to patch a multi-record file, reading it, processing the changes and writing the changes.
It works as smooth as possible, however, due the large amount of records, the writing process takes a long time until all records are written and we may use the resulting file.
Is there anything we can do to expedite the writing process and not wait for until the "buffer" is completely flush?
Thanks
