Description
Currently OMERO.web uses the RawPixelsBean to calculate pixel byte widths and ranges. Under many uses this is fine, but in a case where many requests to an OMERO.web view that uses imageMarshall() are happening use of the bean in the stateful service in this way has a tendency to bring the server to its knees under memory pressure. This is particularly noticable in an OMERO.fs use case where a Bio-Formats reader must be initialized on the source data.
