Additional info for the GPars commit: c1d65be

I've added GPars but configured by default only with a pool of 1 thread. The user can configure this pool with a new property to improve the speed of send the emails.

Regards, Iván.

Thank you :-)

Could you release a new version of the plugin? At least a snapshot?

I think it would be great to update the documentation to include the new configuration options.

Regards, Iván.

Haré la versión nueva el fin de semana próximo. Quiero hacer un refactoring y crear unos testes.

Some performance results in case you're interested.

All these tests has been executed in my local machine (Intel Core i5 12 GB RAM with Linux) against a fake local smtp server that only counts the emails.

Now I've uploaded a test version to our preproduction environment that send emails using Amazon SES API and the results hasn't been so good. I've sent approximately 250 emails per minute using a 10 pool gpars size. I think I've reached our instance or Amazon SES limitation. For the moment this improvement is enough for us because we were sending arround 40 emails per minute.

Regards, Iván.
