Generally I think marketo is a fantastic product, but the thing I'm finding really lets it down is its speed. Sometimes I do very basic queries and I have to go make a few cups of tea before it has run.
Can I please request that you invest more in your servers and concentrate on getting the speed issue fixed. If you do this, you'll easily have the best product in the market (I've used alot of the others!)
So, we've invested a ton in this area since 2012- speeding up form submits, Smart Lists, Email and Trigger Throughput, the SFDC sync, the UI, and most recently List Import.
This is an area of continual improvement for us, but I'd love to have a specific conversation about what is and isn't fast enough. So, I'm going to mark this idea as done- done not in the sense that we've done everything, but done in the sense that I think we're on to the next phase.
Post another idea and be specific if there is something you think should be better. I'll be keeping an eye out for 'em.
