What's New

Plug-In Interface for Integration with Code-level Diagnostics Tools

SilkPerformer offers a plug-in framework for third-party diagnostics tools to provide top-down analysis of errors and performance problems starting from the end user view down to the individual component/line of the application code. SilkPerformer's TrueLog Explorer and Performance Explorer provide seamless linkage to diagnostics tools, minimizing the time to detect the root-cause of performance bottlenecks and load dependent errors.
When analyzing individual user sessions in TrueLog Explorer you can drill into third-party diagnostics tools for a detailed performance and error analysis of single execution paths.
Plug-ins that implement the Performance Explorer diagnostics interface can be called from the Overview Report/Ranking section, thus providing performance breakdown information across all virtual users for each ranking measurement.

SilkPerformer 2006 ships with a plug-in for dynaTrace Diagnostics which provides in-depth Java/J2EE and .NET application performance and error diagnostics down to the code level.

Borland StarTeam Integration

SilkPerformer 2006 supports integration with Borland's StarTeam 2005 that enables you to manage and share your SilkPerformer project files, test scripts, custom include files, and data files.
SilkPerformer's source control integration with StarTeam supports file check-in, check-out, get-latest-version, and other functions typical for source control systems.

To learn about the StarTeam 2005 integration, see the SilkPerformer User Guide, chapter 'Source Control Integration'.

User Guide

SilkPerformer 2006 ships with a new User Guide that is also available as PDF.

System Requirements

Each computer that is to be used in a load test must meet the minimum hardware and software requirements listed below.

For details about SilkPerformer performance and scalability, please see the Performance and Scalability Matrix below.

Hardware Requirements

To install agent software, or both controller and agent software, and use the full potential of SilkPerformer to run heavy load-tests, your system must meet the following minimum requirements:

Load Testing

System Area Requirement
Processor Pentium IV or equivalent CPU
RAM 512 MB (1024 MB recommended)
Virtual memory Three times as much virtual memory as RAM
Network Windows network with TCP/IP (when using remote SilkPerformer agent computers)
Network adapter 10 MBit (fast Ethernet recommended)

Recording, Monitoring, and Scripting

To use SilkPerformer functionality only for traffic recording purposes, monitoring and scripting, the following minimum system requirements are sufficient:

System Area Requirement
Processor Pentium IV or equivalent CPU
RAM 256 MB
Network TCP/IP

Software Requirements

To install and use SilkPerformer, your system requires a minimum set of software components.

Supported Operating Systems

SilkPerformer cannot be installed on computers running Windows 95, 98, or ME. Windows NT is not supported.

Other Required Software Components

The specific components that are required vary based on installation type. For example, to run SilkPerformer Java Explorer, your system must be equipped with a Java 2 SDK. All required components are included on the SilkPerformer Installation CD. Components can also be downloaded from their respective vendors' Web sites. See the SilkPerformer Installation Guide for full details.

Note:
Web Business App uses Page-based Browser-level API (HTML/HTTP)
Web low level uses Browser-level API (HTTP)
Numbers are based on Intel CPUs.


We recommend using single processor agent computers, as they provide the best cost/performance ratio.


Test Parameters:

The numbers of the table above have been determined using a realistic workload with the following characteristics:

The page structure of all requested Web pages corresponds to very popular public Web pages.
The average think-times of all virtual users were about 32 seconds between each subsequent page view, which is a realistic value.
A single virtual user was emulated with 4 concurrent connections, which is a realistic Web browser emulation.
This means that the number of virtual user simulated corresponds to a realistic number of concurrent users accessing a popular Web site resulting in:

Avg. Hits/page: 39
Avg. page size: 130 kByte
Avg. think time between pages: 32 sec

Formula:

Look up the virtual user value from the "User vs CPU" and the "User vs RAM" graph that match the configuration of your agent machines.
From both virtual user values you have received take the minimum value in order to find out how many virtual users your agent machine supports (Web Business App).

Ex: 1xPIII, 1 GHz, 512MB RAM

1) User vs CPU = 2000 vuser
2) User vs RAM = 850 vuser
Min (1, 2) = 850 vuser

-> Agent machines support max. about 850 vuser
