whats the best approach for load testing Web AS 6.20 ?

Hi there,

has anyone of you any expierences with load and performance testing of Web AS 6.20? We want to run a combined BSP- and SAPGui loadtest. While testing the BSPs can be covered pretty well with the tool we usually use for loadtesting (Segue Silkperformer), the SAPGui testing cant. I know theres a tool called Mercury LoadRunner which can perform loadtests of SAP transaktions but its kinda expensive and therefore not an option at the moment. further SAPs eCATT doesnt seem to be capable of doing loadtests. any ideas?

kind regards,

Christian
