Can anyone recommend any general performance testing courses in the UK. I am interested in general techniques and practises regarding testing performance of client/server and web applications. If possible theses courses should not be tied to any tool vendor.
I am not sure if they still do it for external people (I know that internal people can go on it), but IBM did run a course on performance testing which is non-tool specific. I think it was called PEM (Or something like that), which is for Performance Engineers to increase their analysis, strategy and performance planning skills.
Try looking at the IBM Learning Services web site for the UK.
