Category: General / Other Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: michael michaud (michaudm) Assigned to: Nobody/Anonymous (nobody) Summary: Menu slow down Initial Comment: A co-worker has worked several days with the same project (same opened session). Day after day, the menu items took more times to be opened. After a few days, it was unbearable, I closed the project and started a new OpenJUMP and menus were fast again. I cannot reproduce the problem though. Particular context was : - layer manager contained WMS layer, RunDatstoreQuery Layers, vector layers, the person opened many attribute windows without closing them. I tried to reproduce this context but could not reproduce the slowdown. ---------------------------------------------------------------------- >Comment By: ede (edso) Date: 2013-04-24 02:06 Message: something similar was the reason i optimized MrSid. once an image was loaded OJ became very unresponsive, slow menus etc. once i removed the MrSid image layer or made it invisible speed was restored. i found that the image was converted and reloaded in the paint() method on every call, which is senseless as the view port is painted lot's of times, without the bounding box changing or similar, so no need to actually reload the image. hence i introduced a caching that only reloads if really necessary, if not simply redraw the image already in memory, et voila ;) speed again. maybe there is a similar issue in the wms or some other referenced image code? ..ede ---------------------------------------------------------------------- Comment By: mentaer (mentaer) Date: 2013-04-23 14:26 Message: how about the undo chain? or doing a garbage collect of the ram? Are WMS images stored as intermediate results somewhere? on the other hand: could be everything... even the VM. Are you trying to reproduce now on your colleagues computer? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=679906&aid=3611607&group_id=118054 ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
