I believe that the problem is with antivir, but I can't found it (yet). mmmm... that is bad !! :-(

(0007871) marioeirea (reporter) 2012-05-16 06:21	Setting the following values in /etc/dansguardian/dansguardian.conf fixed it for me: maxchildren = 400 minchildren = 32 minsparechildren = 15 preforkchildren = 8 maxsparechildren = 64 maxagechildren = 4000 Looks like these values where changed from 2.5 going forward, severely reduces the number of connections that can be open at the same time. Change it in the tmpl file if you want the values to stick.

(0007875) victorhugops (reporter) 2012-05-26 18:08	Hi, that is interesting too http://bugs.endian.com/view.php?id=3432 [^] In my case, when the user visit a streaming site.. the havp take many time (and all threads) to process each one of that connections. :-(

(0007923) anand_apscan (reporter) 2012-06-20 07:32	Hi, I am using endian for the first time, i dont have much idea abt endian, someone please help me how to edit $MAXCHILDREN value in /etc/dansguardian/dansguardian.conf.tmpl file. maxchildren = $MAXCHILDREN minchildren = $MINCHILDREN minsparechildren = $MINSPARECHILDREN preforkchildren = $PREFORKCHILDREN maxsparechildren = $MAXSPARECHILDREN maxagechildren = $MAXAGECHILDREN

(0008022) fqureshi (reporter) 2012-08-27 02:02	@ anand_apscan You can do the following: nano /usr/lib/efw/dansguardian/default/settings change the values as below: MAXCHILDREN=500 MINCHILDREN=128 MINSPARECHILDREN=32 PREFORKCHILDREN=16 MAXSPARECHILDREN=256 MAXAGECHILDREN=10000 Also if you are facing slow browsing issue change the following values: nano /var/efw/havp/settings change 2 values as below MAXSERVERS=150 SERVERNUMBER=50

(0008331) ipanema211 (reporter) 2012-11-22 20:43	I have reason to believe it has something to do with havp /var/efw/havp/settings does not exists on my 2.5.1 and creating it does not solve the problem. Changing the dansguardian settings to above didn't do the trick for me neither. Disabling anti virus on all content filter profiles solved the performance issue
