According to "RDP Performance Whiatpaper.docx"(http://download.microsoft.com/download/4/d/9/4d9ae285-3431-4335-a86e-969e7a146d1b/RDP_Performance_WhitePaper.docx): "With ClearType enabled, fonts are transmitted as bitmaps and not as glyphs. RDP does not transmit these bitmaps efficiently, resulting in increased bandwidth consumption. ".   Since we want to decreace the bandwidth consumption over RDS session,we did: 1. Keep "Font Smoothin" unchecked on RDS Client 2. Keep "Always use ClearType for HTML" unchecked on Server IE7   In order to easily tell which parts is transmitted by glyph order,we use an open source RDS client FreeRDP(www.freerdp.com),with a tiny modification: 1. Enable GLYPH,FAST_INDEX,FAST_GLYPH orders support by:   Settings->OrderSupport[NEG_GLYPH_INDEX_INDEX] = TRUE;

Settings->OrderSupport[NEG_FAST_INDEX_INDEX] = TRUE;

Settings->OrderSupport[NEG_FAST_GLYPH_INDEX] = TRUE;

2. Make sure "PERF_ENABLE_FONT_SMOOTHING" not enabled by "PerformanceFlags"

3. Disable GLYPH rendering function calls. After that,connect Server,open IE,visit "http://www.msn.com".

The result turns out that IE fonts are transmitted as bitmaps,not as glyphs, but other windows program seems ok. 

Am I missing something ?
