Depends on the time distribution (CPU/IO) for each request
and the usage of synchronisation in your application.

The typical behaviour on a single processor machine
should be between the figures you see and the figures 
that your boss expects.

> Hello,

> The system of my company consists of an Apache + Tomcat 3.2 
> server and a database server. An application is being 
> developed, it involves calling a tomcat servlet which 
> retrieves records from the database server and then use the 
> records to build an XML. I've tested the times required to 
> run from 1000 to 20000 records for a single client, and then 
> tested the times for 4 clients. I found that the average time 
> needed for 4 clients to build the XML with 'n' records is 
> always similar to the time needed for a single client to 
> build with '4n' records(excluding the time to fetch the 
> database). Is this pattern reasonable? My boss suggests that 
> 4 clients to build 'n' records should be similar to a single 
> client to build 'n' records as servlets involve some kinds of 
> threading mechanism. If it is true, what are the means to 
> improve to get a better pattern? Please give me some opinions, thanks.
