PQ60807: WebSphere 4.0.3: Performance problem with
processing of HTTP headers
Downloadable files
Abstract
Performance degradation with processing of HTTP headers in
WebSphere® Application Server V4.0.3.
Download Description
PQ60807 resolves the following problem:
USERS AFFECTED:
WebSphere Application Server users via an HTTP client, such as a browser.
PROBLEM DESCRIPTION:
The processing of HTTP headers in WebSphere Application server was not
optimal, & more CPU cycles have been used for their processing, than
necessary. Overall performance of WebSphere Application Server may be
affected.
PROBLEM CONCLUSION:
A new Java 'String' object has been created for each HTTP header name.
HTTP header names are generally well-defined, so now we cache these names
to avoid of having to create a new 'String' object. HTTP header processing
is now significantly more efficient.
