ACT! Tests Performed by Sage
Sage runs ongoing, automated tests to gauge the performance of the most frequently executed ACT! tasks for all versions of ACT! (see the Appendix for the list of ACT! tasks tested). After each software version is developed, Sage performs these automated tests on hardware that meets the ACT! minimum system requirements and identifies a “worst case scenario” for product performance. We then compare test results for each new version to its previous versions to give a clear picture of performance trending, version by version.

The above chart combines the total time it takes for the ACT! application to launch and open a database. These record as two events, although users may view them as a single operation. The increase in startup time from ACT! by Sage 6.0 to ACT! by Sage 2005 (7.0) and up occurred because ACT! 2005 incorporated a true relational database to provide significant product improvements - including multiple user scalability - but caused a slower startup performance when compared to ACT! 6.0.
As shown in Figure 2, ACT! by Sage 2009 (11.0) has reduced the time necessary to launch ACT! and open the database compared to ACT! 2005.
Other application areas have experienced dramatic performance improvements version over version. Figure 3 shows that various often-performed ACT! tasks run faster in ACT! 2009, by percentage, when compared to ACT! 6.0.

These tests show that ACT! starts much more quickly with a faster hard drive.
  40-50% faster with a faster hard drive•
   6-13% faster with twice the memory•
In the second set of tests (results shown in Figure 6), a 2 GHz CPU was tested with varying degrees of RAM and hard drive speeds.

Rex

These tests showed the most dramatic improvement in ACT! startup performance when using faster hard drives.
20-45% faster with a faster hard drive•
10-20% faster with twice the memory•
The third set of tests (results shown in Figure 7) were performed on a 3 GHz PC, with varying degrees of RAM and hard drive speeds.

Recommendations for Improving Startup Times
Based on the preceding test results, Sage offers the following recommendations to improve
individual performance

Individual users can maximize ACT! startup performance by leveraging the appropriate hardware. Users currently using lower-performing hardware can experience the most dramatic increases in individual performance by ensuring that their PCs are equipped with the fastest hard drives available.
To achieve optimum ACT! start up performance, select a PC equipped with at least 1 GB RAM, a 2 GHz or better CPU, and hard drive speed of 7200 RPM or better.

Operational Performance
“Operational performance” refers to the speed at which a user can switch from one open application to another open application and have the application react to user commands. For example, a user might work in Microsoft® Word and then switch to ACT! to enter a contact. The speed at which ACT! responds to the user’s commands, after making it active, is operational performance.
Factors Affecting Individual Operational Performance
Multiple factors affect operational performance. The main factors are:

   Number of open applications or application instances•
   Physical and Virtual Memory (disk) swapping •
   Processor speed, physical memory, and drive speed

Rex

How do these factors affect performance?

Number of open applications/instances – The number of applications open at any given time will • affect system responsiveness overall, since each open application or instance consumes system resources in order to operate. The more open applications, the more system resources are consumed. It’s important to note that the amount of resources that an application will use varies from application to application.

Physical and Virtual Memory (disk) swapping – As users open and activate an application, • Microsoft Windows® will swap out fast RAM memory used by other applications and free it up for the now-active application. Windows will swap out the now-inactive application memory needed for hard drive-based Virtual Memory, which is slower, freeing up the RAM for the active application. Although Virtual Memory disk-swapping makes the newly active application run faster, users can experience a performance problem when switching back to the inactive application, if the PC does not have enough available RAM for both open applications.

Processor speed, physical memory and hard drive speed – CPU (processor) speed, physical • memory, and hard drive speed can all impact operational performance, but at different levels. Faster CPUs and hard drives (RPM), combined with faster and larger physical RAM, enable
a user to move between applications more quickly and allow the application to react faster to
a user’s commands.

Rex

How do the above factors fit together? When active, ACT! consumes 130–150 MB of physical memory (RAM). If a user switches to another application, such as Microsoft Outlook®, Windows will free enough physical memory to accommodate the newly active application. If there is not enough RAM for Outlook to run, Windows will swap out the RAM being used by ACT!, exchanging it for virtual memory space on the hard drive, and free up the RAM for Outlook to run. This swapping can cause a delay in the time it takes for Windows to “paint” or render the application for use.

Through operational performance testing, Sage recommends the following configurations (Figure 9), taking into account the number of applications an individual user will have open.

As seen in Figure 9, 1 GB of RAM is recommended for speedy operational performance as users move from one open application to another if throughout their workday they use ACT!, plus keep three to four additional applications open
