performance - GRAILS 2, memory issues -


We have an application using Grails 2.0.1 and MongoDB and as our user base has increased and we have some Performed research, we have found that grails eat approximately 150 MB of RAM for each normal request, and when the RAM is about to reach the maximum, it does it to GC We have put singleton mode for controllers, and are non-functional for services. We use JRokit.

I should know whether this Grails can be considered normal for app or not. Our website is nothing more than the general website, there is no extra memory usage, just one user management system and code are okay.

Here are the plugins we are using: 

  app.grails.version = 2.0.1, app.servlet.version = 2.4, app.version = 0.1, Plugins.cache-header = 1.1.3, plugins.code-coverage = 1.2.5, plugins.codenarc = 0.12, plugins.crypto = 2.0, plugins.gsp-ass = 1.3 plugins.jaxrs = 0.6, plugins.mongodb = 1.0 .0.RC5, plugins.navigation = 1.2, plugins.quartz = 0.4.2, plugins.redis = 1.0.0.m9, plugins.rendering = 0.4.3, plugins.selenium = 0.8, plugins.selenium-rc = 1.0.2, plugins.spring-security-core = 1.2.7.2, plugins.springcache = 1.3.1, Plugins.svn = 1.0.1, plugins.tomcat = 2.0.1, plugins.ui-display = 1.2.2 < / Code>   
 
 
 On a Sun JDK, jvisualvm (or jrockit equivalent, if there is one, fire) Otherwise, give yourself a proper prof The Ilr who works with jrockit, attach your servers running, start profiler and analysis of the production is to consider where you'll have an idea.  
 Perhaps you are actually loading more information than backend storage but this is just an estimate.

java - NullPointerException for a 2d Array -

नक्शा = नया बफर्ड इमेज [चौड़ाई] [ऊंचाई]; के लिए (int i = 0; i & lt; height; i ++) {for (int j = 0; j & lt; चौड़ाई; j ++) {if (charMap [j] [i] == पर्वत। इंडेंटफार्म) {if (j + 1 & lt ; चौड़ाई और amp; amp; j-1 & gt; = 0) {if (charMap [j-1] [i]! = पर्वत। इंडेंटिफ़ायर & amp; amp; & amp; amp; charMap [j + 1] [i]! = पर्वत। इंडेंटफार्म) {नक्शा [जे] [आई] = टाइल ग्रिड [1] [10]; }} और {नक्शा [जे] [आई] = टाइल ग्रिड [8] [10]; }}} यह कोड है जिसे मैं सेल के चारों ओर प्रत्येक टाइल को चेक करके 2 डी सर की जांच करने के लिए उपयोग कर रहा हूं लेकिन मुझे लगता है कि किसी को भी सोच रहा हूँ मदद कर सकता है? मुझे संदेह है कि आपको NullPointerException को charMap [j] से प्राप्त हो रहा है [ I] == पर्वत। इंडेंटिफ़ायर लाइन। सुनिश्चित करें कि आप ज्योफ द्वारा सुझाए गए दोनों मानचित्रों के लिए आंतरिक सरणियों को प्रारंभ करते हैं।

python - Assemble mpeg file unable to play in mediaplayer -

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part. Problem 1: When I run the file in the media player, it will play the video until it reaches that segment which I left Give it Example: Chunk = ["yui_1", "yui_2", "yui_3", "yui_5", "yui_6"] Duration of each segment: 1 second * If you think I have left the "yui_4" section. * If I went to collect all the parts except "yui_4", then the video will play the first 2 seconds before being hanged throughout the period. Problem 2: When I gather the first part off the part, it is unable to run the full MPEG file is. Duration of each piece: 1 second Example: wheel = ["yui_2", "yui_3", "yui_4", "yui_5", "yui_6"...
