Abstract: A system for performance testing a web application initializes to be instrumented a subset of methods of the web application to be tested in response to a request, and then tests the application based on the subset of methods. The system generates an instrumented call tree and corresponding stack traces for each request in response to the testing, and determines one or more methods that take longer than a predetermined time period to execute using the instrumented call trees and the stack traces. The system then determines additional methods to be tested and adds the determined additional methods to the subset of methods and repeats the testing.

Abstract: A process for treating trees and bushes having a xylem structure through which sap passes so as to provide trace elements or micro-nutrients selected from calcium, zinc, magnesium, iron, manganese, copper, molybdenum, nickel and boron to the tree or bush, comprising inserting into the xylem structure a solid glass article comprising a phosphate base glass containing the trace elements or micro-nutrients in oxide form, the formulation of the phosphate base glass being selected so that the solubility of the phosphate glass in the sap of the tree or shrub being treated is sufficient to provide a transfer of the said trace elements or micro-nutrients from the glass into the sap by dissolution of the glass.
