Sun Java System Web Server 7.0 Update 4 Performance Tuning, Sizing, and Scaling Guide

Static Content Test

This test was performed with a static download of a randomly selected file from a pool of 10,000 directories, each containing 36 files ranging in size from 1KB to 1000 KB. The goal of the static content test was to saturate the cores and find out the respective throughput and response time.

This test used the following configuration:

Table 6–3 File Cache Configuration

Default 

Tuned 

enabled=true

max-age=30 sec

max-entries=1024

sendfile=false

max-heap-file-size=524288

max-heap-space=10485760

max-mmap-file-size=0

max-mmap-space=0

enabled=true

max-age=3600

max-entries=1048576

sendfile=true

max-heap-file-size=1200000

max-heap-space=8000000000

max-mmap-file-size=1048576

max-mmap-space= l

max-open-files=1048576

The following table shows the static content scalability results.
