I just got this mail from someone who’s using my HttpCompressionModule.
He took it upon himself to do some performance testing on the module and here are
the results:
Tool:
Microsoft’s free “Web Application Stress” tool.
Network:
WAS ran on a server with a T-3 Internet connection to the test server.
Test Server:
Windows 2003 Server
~1800 MHz AMD CPU
500 Megs RAM
WAS Settings:
All default except:
Stress Level (threads) 60
2 sockets per thread
Test Run Time: 3 mins
RESULTS:
Without HttpCompressionModule
CPU Averaged 31%
Number of hits:
23,908
Requests per Second: 133.37
TTLB (Time to Last byte) Avg: 639.31
Resultant File Size: 6807 bytes
WITH HttpCompressionModule
(deflate and gzip nearly same results)
CPU Averaged 97%
Number of hits:
56,221
Requests per Second: 311
TTLB (Time to Last byte) Avg: 317.17

Interesting!
