Capacity Management - Visio Services limits

Limit	Maximum value	Limit type	Notes
File size of Visio Web drawings	50 MB	Threshold	Visio Services has a configuration setting that enables the administrator to change the maximum size of Web drawings that Visio processes. Larger file sizes have the following side effects: Increase in the memory footprint of Visio Services. Increase in CPU usage. Reduction in application server requests per second. Increase overall latency. Increase SharePoint farm network load
Visio Web drawing recalculation time-out	120 seconds	Threshold	Visio Services has a configuration setting that enables the administrator to change the maximum time that it can spend recalculating a drawing after a data refresh. A larger recalculation time-out leads to: Reduction in CPU and memory availability. Reduction in application requests per second. Increase in average latency across all documents. A smaller recalculation time-out leads to: Reduction of the complexity of diagrams that can be displayed. Increase in requests per second. Decrease in average latency across all documents.
Visio Services minimum cache age (data connected diagrams)	Minimum cache age: 0 to 24hrs	Threshold	Minimum cache age applies to data connected diagrams. It determines the earliest point at which the current diagram can be removed from cache. Setting Min Cache Age to a very low value will reduce throughput and increase latency, because invalidating the cache too often forces Visio to recalculate often and reduces CPU and memory availability.
Visio Services maximum cache age (non-data connected diagrams)	Maximum cache age: 0 to 24hrs	Threshold	Maximum cache age applies to non-data connected diagrams. This value determines how long to keep the current diagram in memory. Increasing Max Cache Age decreases latency for commonly requested drawings. However, setting Max Cache Age to a very high value increases latency and slows throughput for items that are not cached, because the items already in cache consume and reduce available memory.
