Otherinbox is slowing down!

Hey! I've been using OIB since you guys posted some early beta invites on techcrunch (a long time ago!) and back then I don't recall that otherinbox was so damn slooooow. I mean what happened?

I have a brand new sony vaio (Intel Core 2 duo, 4G DDR2 SDRAM, ...) laptop with a dual boot (linux and vista). I connect to the internet trough a DSL cable and I'm using:
- Mozilla/5.0 Gecko/2009042316 Firefox/3.0.10
- Google Chrome 1.0.154.65

I did some simple stopwatch testing and here are the results:

Chrome:
- opening OIB: 9 sec
- clicking on a folder with 100+ emails: 16 sec for the emails to show up
- marking 100+ emails as read: 20 sec

Firefox:
- opening OIB: 5sec
- clicking on a folder with 50+ emails: 21 sec for the emails to show up
- marking 100+ emails as read: 18 sec

I don't know about you guys, but I think that your service is very very very slow! A task of reading my daily mailing lists shouldn't take that long.

I must say I was very enthusiastic when I first signed up and replaced my gmail with a otherinbox email on facebook, twitter, used OIB as my primary mail for college mailing lists subscription (it's very important to me to have those college mailing lists organized), ... but now OIB is becoming a slow and kinda irritating service, that will force me to change my email settings for all the services that I use on a daily basis.

I think you guys should go back to the drawing board and come up with a service that is as fast as gmail (or faster!)

Kind regards, Tomaž
