Interesting read about Java

Interesting, you are the second person to independently
refer this to me ...
The interesting bit was the bit on the combination of rational rose
with Java on Solaris -

2. The JRE is very large.
The JRE is significantly larger than comparable runtime environments
when considering resident set size (memory dedicated to this specific
program). It has been seen to grow to as much as 900M. This has a
drastic effect on both performance and resource usage. It also means
that multiple JREs present critical resource constraints on the
servers for such thin-client systems as SunRays. Typical resident set
requirements for Java2 programs include:
Hello World 9M
SMC Server 38M
SLVM GUI 60M
Component Manager 160M
TogetherJ 300 - 900M
The largest program in that list is TogetherJ. From the standpoint
of resource requirements, TogetherJ does much of what Rational Rose
does but Rational Rose appears to function in less than 250M. Startup
time is effected as well. For example, on an Ultra10 TogetherJ
requires 5 minutes to load and start. SMC, Sun's flagship system admin
console, takes between one and two minutes to reach the point that it
can be used.
