Hello all, It seems that XPath selection is several orders of magnitude slower in Mono 2.0 on Ubuntu than on C# on Windows XP.
The example below is pretty straightforward, and doesn't seem like it's much slower, but we do this millions of times a day. In some cases, I've seen parsing a document go from 10 ms on Windows to over 2000 ms on Mono 2.0/Linux. I've made a Mono Project to let you test it yourselves: http://www.giborama.com/TestSlowXML.tar I've advocated the switch of our company's platform from Windows to Linux, but XML/XPath is an essential part of the business, and with it being so slow, we're dead in the water. I would greatly appreciate any help you may have :) ~~~~ Windows XP / C# 2005: Xpath: //head/title took 2 Xpath: //[EMAIL PROTECTED] 'content']/div[starts-with (@id, 'p')] took 0 Xpath: .//h2/a took 0 Xpath: .//[EMAIL PROTECTED] 'byline']/a[position()=1] took 0 Xpath: .//[EMAIL PROTECTED] 'byline'] took 1 Xpath: .//h2 took 0 Xpath: .//[EMAIL PROTECTED] 'post']/div[starts-with (@id, 'pc')] took 0 Xpath: .//[EMAIL PROTECTED] 'post']/div[starts-with (@id, 'pc')]//img took 0 Xpath: .//[EMAIL PROTECTED] 'post']/div[starts-with (@id, 'pc')]//a took 0 Xpath: //[EMAIL PROTECTED] 'paging']/[EMAIL PROTECTED] 'alignright arrowforward'] took 0 Ubuntu / Mono 2.0: Xpath: //head/title took 24 Xpath: //[EMAIL PROTECTED] 'content']/div[starts-with (@id, 'p')] took 8 Xpath: .//h2/a took 1 Xpath: .//[EMAIL PROTECTED] 'byline']/a[position()=1] took 5 Xpath: .//[EMAIL PROTECTED] 'byline'] took 3 Xpath: .//h2 took 1 Xpath: .//[EMAIL PROTECTED] 'post']/div[starts-with (@id, 'pc')] took 5 Xpath: .//[EMAIL PROTECTED] 'post']/div[starts-with (@id, 'pc')]//img took 5 Xpath: .//[EMAIL PROTECTED] 'post']/div[starts-with (@id, 'pc')]//a took 5 Xpath: //[EMAIL PROTECTED] 'paging']/[EMAIL PROTECTED] 'alignright arrowforward'] took 8 Cheers, Bradford _______________________________________________ Mono-list maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-list
