Batch add emails to PST

Hi,
As we discussed this in previous topics, after some size of PST, there performance degradation.
I see about a minute to add email to PST (28GB size) with already 113k messages. But, maybe there’s an option to make batch add, where emails will be added in batch and maybe this can be done faster ?

Thanks

@slavago,

Yes, you can add message to PST in bulk using the FodlerInfo.AddMessages method. Please try it at your end and let us know your feedback.

Thanks,
Is this method really do bulk, or it’s iterating internally and actually doing one by one insert ?
Thanks

@slavago,

The AddMessages method is comparably fast and should perform better. However, for a PST of 28 GB size, the effect may be minimal as we recommend to have an average PST file size of 5 GB.
