Faisal, relative stroking is supposed to process faster. If you suffer from performance problems you're dealing with complex drawings- guessing. In general, since the parsed dom eats up your machines ram, any optimization that reduces your drawings dom memory footprint might be worth thinking twice. Adjusting the coordinate representation to a reasonable resolution is easy. Relative stroking throughout the entire drawing should give you smaller numbers too. Play around with grouping and inheritance for styling: redundant info that gets stripped from the file won't squat in a mem;-)
