Slow Activity Stream on Oracle based wikis

Pages containing an activity stream load very slow on Oracle based wiki. This also includes Main.WebHome.

• after adding some messages in Message Stream, Main.WebHome loads faster.
• After deleting them, the page is slow again. Repeating this cycle again, will make Main.WebHome to load normally (at normal speed)

Aprox loading time is ~8-10 seconds, which is very much
