It's great to see multiple products in the market trying to solve this problem and I admire your ability to do so without a large team or any funding. It's unclear how the market will grow in the future but we're thrilled to see Optimizely grow +397% amongst the top 10,000 websites in the last year to over 2,500 happy customers.

I'm glad to see you are focusing on improving your response time. Unfortunately hitting live servers serving dynamic content in 5 locations is never going to be able to beat 100,000 edge-cached nodes in 75 countries serving static content when it comes to response time and reliability.

According to the link you provided it looks like Pingdom reports VWO response times as:

VWO Slowest Average: 352ms

VWO Overall Average: 207ms

VWO Fastest Average: 45ms

According to Pingdom, Optimizely response times are:

Optimizely Slowest Average: 95ms

Optimizely Average: 65ms

Optimizely Fastest Average: 19ms

Here is a head-to-head comparison of Optimizely vs. VWO including response time and feature differentiation: http://i.imgur.com/BRTxC.png

You are right we don't currently offer ancillary features like heatmaps and usability testing. We've been focused on offering the best possible experience for A/B and multivariate testing.
