We deployed the site on a couple dozen Xeon servers running Red Hat linux. We're using Struts, Tiles, Hibernate, Velocity, & Spring and the performance is great.

Michael,

Congrats, great job!

Are you using Nukes by any chance?

There were a few performance-related issues we had to address with our deployment at Bolt with respect to Hibernate and SQL Server. One, in general, was that the current release of Hibernate does not support locking hints so I had to rewrite some of the Hibernate classes to introduce the NO LOCK clauses following our SELECT clauses in SQL Server. All in all though, it's been amazing deployment and things are running very smoothly now (15 Linux boxes) and a peak during the day of 15,000 concurrent users.

Hi Michael !
Sorry for the late (but never too late) message but I was on holiday.
So, congratulations !
Why some parts of your site continue to use another technology (.asp, for instance) ?

Thanks.
Creatura.

Well....

I have got a small site running JBoss. About 1000 visitors a day. The site is reasonably complex - light pages are about 10 database requests, the heavier pages need up till 1000 database requests.

Before JBoss I had the same war's where running flawlessly on Tomcat (for years). Since i moved to JBoss there are a dozen different reasons that crashed my website. Crash means crash and no recovery. With help of the the server.log I have solved most of problems but still the website by far lacks the stability of my previous Tomcat set up.

For Bolt - do decent load testing. My JBoss worked fine in development - but the first days in production it had a TTL of 1 - 2 hours. (Now the TTL is about 24 hours - just enough to restart it only once a day!)

To get my website running production level with Tomcat is a matter of weeks. With JBoss you should be counting on a learning curve of several months (i am not there yet!). Unless of course you have a Mickey Mouse website.

Congrats on the deployment success. Are you running clustered/farmed? Sessions replicated? How many instances?

I'm looking for any guidelines on the largest successful cluster deployment with jboss/tomcat.

Hello Michael,

What database do you use for bolt.com.
Can you give me an idea of the size?
If you say 15.000 concurrent users, how many requests do they send?

Thanks.
