I have a couple of apps that implement regular expressions using vbScript.RegExp extensively and have not any material difference on any of the XP, 7 or 8.
Some issues with 64 over 32 but minimal and that is only around a 3% difference in processing time. The processes run for a couple of hours so enough time to see a difference if there were one. In regards to regexp - can make a big difference on how they are written especially if it results in many back steps to resolve. I found writing in a particular way made a very significant impact on performance - maybe something along those lines but one would assume performance should be similar across platforms regardless. -----Original Message----- From: ProfoxTech [mailto:[email protected]] On Behalf Of Paul Hemans Sent: Monday, 4 August 2014 12:45 PM To: [email protected] Subject: String operations under Win 8 I have a VFP process that does a lot of string manipulations and some regular expressions through vbscript.regexp. It runs fine under XP, 2003, 2008 server etc but it takes forever on Windows 8. Multiple Win 8 machines have been tested against. Process takes 7 minutes on a 2008 box, and about 1 hour under Windows 8 Unfortunately it is a big process (a compiler/translator) and so it is difficult to isolate what is causing the issue. 1 core of the CPU is maxed out Memory usage of the process is roughly 30MB I was wondering if anyone has had issues with VFP9 under Windows 8 in terms of performance? --- StripMime Report -- processed MIME parts --- multipart/alternative text/plain (text body -- kept) text/html --- [excessive quoting removed by server] _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://mail.leafe.com/mailman/listinfo/profox OT-free version of this list: http://mail.leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/[email protected] ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
