Category: XML Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: winston (wwinston) Assigned to: Nobody/Anonymous (nobody) Summary: MonetDB4/XQuery Extremely Slow on Vista 64-bit Initial Comment: I installed MonetDB4/XQuery 32-bit on (1) Windows XP 32-bit, and (2) Windows Vista 64-bit. I need to use the exact same MonetDB version. For example, when I compare the two using the XPath (XQuery) "//open_auction//description//listitem//keyword" on XMark database size=0.005: (1) On Windows XP the query takes: 0.016 seconds and returns 47 rows. (2) On Windows Vista the query takes 18.7 seconds to return the same 47 rows. This demonstrates that Vista runs this application 1000x SLOWER than on Windows XP. The computer is a new Dell laptop, with 8GB Ram and 2GH processer. The processor speeds are the same on the XP and Vista boxes. I uninstalled the McAfee virus checker thinking it was the problem and installed Microsoft One Care (also installed on the XP machine), but there is no change in the performance. What is going on here? Why is Windows Vista so excruciatingly SLOW for MonetDB, 1000x slower, when compared to Windows XP? Any idea how to improve MonetDB performance on Vista? ---------------------------------------------------------------------- >Comment By: Sjoerd Mullender (sjoerd) Date: 2009-11-02 19:15 Message: Would it be possible to install the 64 bit version of MonetDB on your Vista and try the experiment again? I don't have a 64 bit Vista on bare metal to try this on, and I doubt running it in a virtual machine gives reliable timing results. ---------------------------------------------------------------------- Comment By: winston (wwinston) Date: 2009-10-31 17:37 Message: BTW: The measurements were taken from a Java program using the 1.14 client jar. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=482468&aid=2889989&group_id=56967 ------------------------------------------------------------------------------ Come build with us!
