You may have noticed some lag at times when using Zapread. That's because the server has been a cheap shared server. Not for long.
Zapread.com will be moving to full cloud hosting. The test site at https://zapread.azurewebsites.net/ is up and is not yet fully resourced. The concept looks good and soon we'll be making the switch. The nice part about the new host is that it can scale up and out with only a few clicks. The current server is their "free" tier, which works well enough.
It seems that having server RAM is a major bottleneck, and the old service only provides 300MB. that limit is hit almost instantly (250MB just to start the service). This results in many server resets. The new service starts at 1GB of ram and goes up from there.
