LiteSpeed seems to be easy to configure to handle multiple Rails apps. I meant on a single EC2 instance, just to be clear. LiteSpeed seems to be easy to configure to handle multiple Rails apps.

I, too, am not a sysadmin and I would like to (easily) deploy my apps using Capistrano and LiteSpeed. I tried the SliceHost forums, but no luck so far. Bobby Steve,

Why litespeed. I saw a posting one time from Zed Shaw, saying he recommends litespeed for those that are not experienced system admins. I think he was trying to save himself some support tickets for Mongrel. It has a good admin gui and quick commercial tech support. Performance is as good or better than other configurations, depending upon whose doing the testing. Plus, I saw that techno-weenie was using it (don't know if he still is). All those things made it seem like a good fit for me. Hi Sean,

Performance reasons? I’m interested in you decision to go with litespeed. Performance reasons?

The problem was not related to EC2. I think I have identified and fixed the slowness problem. I was serving my entire rails public directory from S3, as you identified. I was also fragment caching much of my site from S3 as well. As an experiment, I was trying to serve as much of quizical from S3 as I could. I'm still serving cache fragments from S3, but have moved the serving of the public directory back locally. That seems to have helped a great deal. Another problem that might have been causing slowness is that I was ran out of room in my main EC2 partition. Amazon gives you ~10GB in the main partition, with the rest of the 165GB in their "ephemeral storage" located on /mnt. I had my database stored in the sda1 partition and, along with rails apps and applications, quickly consumed all the 10GB. I've now moved my database to /mnt. Thanks for the feedback.

Using Firebug, I’ve gone to Quizical several times over the last week and eyed the network load times. Consistently it appears that quizical.net itself loads in under 50ms (median ~20ms, makes since if it’s a LiteSpeed cache). But I'm also seeing that all your other assets that are hosted from quizical.s3.amazonaws.com load very, very slowly. I’m seeing times with a median of 500ms and maximums of 2secs. I know it’s not my end as I’m on a direct Fiber line from work and a cable modem from home and have seen the same results consistently. I’ve read the Dr Dobbs report that measured latency off S3 and their results completely contradict this empirical data, but I wonder if the growth of S3 users since that article was written has lowered S3’s performance. I’ve also found anecdotal accounts of folks getting terrible performance overseas from S3. I’m hoping other folks out there can contribute what they’ve seen in terms of load times for Quizical and other services that are using S3. Perhaps, I’m an isolated case, but I’m in Palo Alto, CA so you better hope all the VC’s here don’t have the same load times I’m getting.

It's really good for scaling and you can go three tiers and power machines during peak hours and poweroff when they are no longer needed (of course you'll need load balancing). Thanks :)
