Multi-panel dashboard loading slow in IE7?

[sowings]

I've got a multi-panel dashboard (four searches driving several panels) that's loading slowly in IE7. It seems like it might be waiting for the longest running of those searches before attempting to render any of the panels. Does anyone have any insight into something I could try?

After closer inspection of the dashboard source (advanced XML), I found that there was a two-week search for "*" which wasn't sending its results anywhere. By removing this spurious HiddenSearch, the performance of the dashboard has returned to normal.

Thanks much for insights into the benchmarking results. Hopefully I can move away from IE7 soon!

I've had similar problems with older version of IE, IE9 and IE10 handle DOM/CSS, js more efficiently. I have also encountered IE7-8 tend to crash while running Chart intensive Dashboards after 4-6 hours. I've restored to using using Chrome and FireFox to run my dashboards. Probably not the answer youw want to hear.

If you are using JSCharts:

Different browsers support different rendering technologies, modern browsers have support for SVG but older versions of Internet Explorer do not. IE 6,7 and 8 uses VML technology to render charts. Rendering performance is slower on this browsers. IE 9 has support for SVG and provides excellent rendering performance.

JS Benchmark for IE8 vs IE9 indicates that IE8 is a slow browser with slower Javascript engine.

Splunk 5.0 has JSChart enhancements which focus on improving performance while rendering multiple panel dashboards.

How about upgrading to IE9 or using other browser or using Flashcharts?

At present we are using Flash charts for most of it, but unfortunately, upgrading is off the table at this time. I'll dig further with the info you've provided so far.
