You're welcome. Many software companies have little knowledge, so they keep promising they will look into problems, or that they have a fix but won't say what it is. Even the phpMyAdmin developers may not have tracked down this particular problem.
I also could be wrong. But I did get my phpAdmin to speed up, so I could be right. If I were the developer of a major product like that, I would have tracing code or invest in a good PHP debugger and I would take the time to track bugs down. I guess my priorities are different from theirs.
