For every $2.29 spent on a .NET transaction, the Websphere 6.0 equivalent clocked in at $5.87 per transaction - over two and a half times the cost.
Industry benchmark studies indicate that .NET/Windows platform can scale from 16,000 transactions per minute to over 500,000 transactions per minute.
The IBM WebSphere J2EE/Unix technology, one of the best representatives of the J2EE genre, does no better than a 17,000 to 110,000 range of transactions per minute, at a much higher cost per transaction.
Developer Productivity
.NET development offers significantly lower man-hours of installation, configuration and development cycles to complete
than identical J2EE enterprise applications built to the same specification.
Productivity hindering factors on the java/j2ee platform include too many frameworks (Spring, Tapestry, Velocity, Hibernate, Struts, JSF...) and
too many differences in J2EE spec implementations.
Long Term Maintenance Cost
As reflected in the lower price performance ratio above, the long-term maintenance cost of a .NET enterprise application tends to be lower than the same application developed on leading J2EE app servers
