> Hi,
> we use the camel mail component and noticed a performance issue if we poll a
> mailbox with a lot of messages (30.000+), though we set a small value for
> maxMessagesPerPoll and FetchSize. I found that all available messages are
> looped through multiple times.
> In a test I measured the number of messages processed in 5 seconds for
> different amount of available messages in the inbox before and after
> optimizing the code. MaxMessagePerPoll is set to 3.
> I attach a picture with the results of the measurement.

> This problem affects not a specific version.
> Best regards,
> Manuel
