> Just a quick note that Albany Med has completed it's migration from  
> Sakai 2.4.x to 2.5.x - and is planning on 2.6.x later in the summer.  
> All migrations completed without a hitch (the resources conversion  
> took one of our app servers about 8 hours to convert approximately  
> 100k resources).
>
> It's amazing how much capacity we've gained with a move to 64bit.  
> Our load test which works against a few common tools (resources,  
> schedule, forums, site info, and a few others) saw a max throughput  
> increase of over 10x. (There are also several performance  
> improvements to resources and forums that helped this value  
> significantly). We remain running some contrib tools such as  
> SiteStats - and we have dropped JForum from our install. We have 8  
> homegrown Sakai tools - 6 of them are linked tools that rely heavily  
> on core Sakai services (authz, gradebook, etc). We are also looking  
> at giving Tests & Quizzes another try this year.

> Here's some infrastructure details about prod:

> Old Environment:
> 2 App Servers
> 2x Xeon 2.8ghz
> 4gb ram
> Windows Server 2003 Sp2
> JDK 1.5.0_11
> Tomcat 5.5.23 -Xmx1260m
>
> Database Server
> MySql 4.1.22
> Windows Server 2003 R2 Sp2
>
> File Server
> 1x Xeon 2.8ghz
> 2gb ram
> Windows Server 2003 Sp2
> direct attached storage
> New Environment:
> 2 App Servers
> 2x Xeon 5160 (3.0ghz dual core)
> 8gb ram
> Windows Server 2008 x64
> JDK 1.5.0_18 (AMD/EMT64)
> Tomcat 5.5.26 -Xmx5000m
>
> Database Server
> 2x Xeon 5160 (3.0ghz dual core)
> 8gb ram
> Windows Server 2008 x64
> MySQL 5.0.81 64bit
>
> File Server
> 2x Xeon 5450 (3.0ghz quad core)
> 8gb ram
> SAN attached storage
> Windows Server 2008 x64 (failover cluster - other box is MSSQL)
> We load balance the environment using Citrix Netscaler 7000 in a  
> redundant pair - we don't do full SSL offload (e.g we are https all  
> the way through to the app servers), and we also dropped APR from  
> this config - so it's just standard Tomcat/JSSE for SSL on the app  
> servers. Since the load balancer pools these connections, we do not  
> see any discernable difference between APR and SSL (on 64bit windows).
>
> All in all - our customers are happy!
