Thanks for all the ideas here - much appreciated. What I've found so far is:
- I use ASCIIMathML and the HTMLArea editor which require code in MarkupPostBody and MarkupPreHeader. If I remove this code then the HTMLArea wysiwyg editor is no longer invoked (I presume that means I've removed the code that invokes it successfully) but the slow performance persists. - I also opened an Asciencpad file since that uses a version of HTMLArea and ASCIIMathML too. It performed fine with no adverse effects on the CPU. - bearing in mind that disabling all my plugins doesn't solve the problem either and that my TW's aren't huge (my main test TW is 888K) I'm quite intrigued that I can switch so much off and still tie up the CPU. Those IE6 challenges with slow javascript are starting to look suspicious now although I don't understand why Asciencepad will run OK! - Although I'm no longer suspicious of sync since it does nothing unless invoked manually, I checked the macro error and it merely says "Error while executing macro <<sync>>: [object error]" - I opened a raw TW without any performance problems. I imported all tiddlers from a TW which performs slowly, saved and reloaded. The new TW then performed poorly and tied up the CPU - My main test TW holds approx 160 tiddlers including approx 30 plugins. - My TWs are built from a master which has approx 100 tiddlers including the same 30 plugins. So I must have around 60 content tiddlers. - The ASCIIMathML is displayed (in IE at least) by the MathPlayer. This is uptodate and works on other sites. In practice I don't think it's part of the issue because I'm not actually displaying any maths when the problems begin and its initial splash screen is not displayed even allowing for the poor performance. - Just in case it's significant, I'll note that there's a short period of about a second or two when the TW has opened and displayed the sole default tiddler and when CPU usage drops and mouse responses are normal. Only a second or so later does CPU rise and mouse response takes minutes. - I've yet to find out how to check which hotfixes I have but will do that soon. - I've begun to explore javascript slowness on Google but need to spend more time on that. I'm really hoping that's not the problem because it suggests that my ability to use my TWs is at the whim of hotfixes. I also use my work PC and do not have complete control over what is applied and when. - If I attempt to paste into the editing area in FireFox I get the error about unprivileged scripts being unable to access copy, cut and paste for security reasons. I've seen material somewhere on how to fix this on a single PC but it sounds a bit nightmarish if I want to share my TWs. With all this in mind I'll therefore explore the issues around javascript slowness in ie6 and see what I can learn about my hotfixes.
