I have tested many other feed modules but simple feeds' performance is much better that others.
I have a couple of suggestions to improve it.
1) Original article must open in new window
2) In configuration for limiting no of feeds to be updated per cron job run. (Because updating all feeds in one cron job create many problems and also request time out sometime.)

m3avrck commentedUse hook_link_alter() to change the links to open in a new window. That is not a good general solution and only site specific so use that to fix.
Per cron run feed updates has now been committed.
