One of the most frequently asked questions we get from users is: “How can I optimize FlowJo’s performance?” The short answer is, FlowJo attempts to optimize settings automatically for your machine during installation. How convenient!
The number one cause of sluggish performance in FlowJo comes down to RAM available on a given system. As a rule of thumb, FlowJo requires about 4× the RAM (megabytes or gigabytes) as the dataset loaded into a given workspace. Minimum and recommended system specifications are included with the release notes for each version. To find the documentation for each version, see our website:
If beefing up your hardware does not set your FlowJo at full throttle, check where your data is being stored. Storing data outside the local environment significantly reduces FlowJo v10’s performance. If you must keep your data on the server to maintain space on the local machine, you can save the analyses as ACS files, so you never need to re-associate your raw data with the workspaces.
As mentioned, there is no magic adjustment within the Performance section of FlowJo’s preferences to speed up the application. For more on the particulars of this area, see this documentation page:
