Demultiplexing API Endpoint Performance

In the past, some may have experienced performance and usability issues when demultiplexing large data sets. Clarity LIMS now includes the demultiplexing API endpoint, resulting in performance enhancements that speed up demultiplexing and allow quicker interaction with the data.

While acknowledging that usability is subjective, the Clarity LIMS product and development teams have established usability ratings based on criteria that measure how lab scientists must wait before they can interact with a feature on the screen. These criteria also allow for the comparison of performance and usability across the various screens of Clarity LIMS.

In the following table:

•

Successful user interaction means that a feature can begin to be interacted with (ie, it can be selected, scrolled, moved, and so on).

•

Numbers are provided for guidance only, and differ depending on the RAM and CPU speed of the computer used to view the page.

Usability Rating	Criteria
Good	A successful user interaction (data load) in ~ 2 seconds
Reasonable	A successful user interaction (data load) in ~ 6 seconds
Acceptable	A successful user interaction (data load) in ~ 9 seconds
Degraded	A successful user interaction (data load) in ~ 20 seconds
Unusable	A subjective limit to usability

The following table shows how the usability rating changes as the number of samples in the pool undergoing demultiplexing increases.

Usability Rating	# Samples
Good	2200–2400
Reasonable	3400–3600
Acceptable	4600–5800
Degraded	7200–7400
