I do not speak Portuguese, but let me suggest the quickest and cheapest way to respond to

your customer : buy the amount of RAM needed to run your application, and offer it to him.
The current price is somewhere around 15 US$ per GigaByte.
By the time you end discussing the matter with him, you will have spent much more than that.

And tell your customer that his portable phone probably has more memory in it, than his 

Tomcat is a Java application; your webapp running inside Tomcat is also a Java 
application; and Java needs (comparatively) a lot of RAM to work well.
150 MB is absolutely nothing in that context.  Just for an idea : we have a Tomcat with a

single (and simple) webapp, and depending on the number of users, we allocate up to 2048 
MB to the Java heap for Tomcat.
