I had inherited a template for a database which was taking 3 seconds to open any sort of document. It soon got to be irritating, and I noticed that the little lightning bolt at the bottom left side of the Notes client was flashing wildly, so I fired up the Notes RPC Parser to try and see what was all the traffic about.
The culprit was soon found: it was a subform containing buttons whose label was dynamically computed depending on the user’s desired language. And, unfortunately, it was making an @DbLookup for every single button, and an uncached one at that. If you look at the screenshot, you’ll see that an @DbLookup generates 3 NRPC Calls, for a total of 50ms – and this was done 30 times each time a document was opened.
That, and another issue that I corrected, meant that I could massively improve the performance of the application for only about half a day’s worth of work.
Feel free to use the tool, or if you can’t be bothered, hire me to solve your Notes Client performance issues.
P.S. I’ve just released a new version of the tool Notes RPC Parser, which you can download here:
Thanks for update of Parser!
