CIFS access very slow

[bob_sauvage]

Hi there,

I'm using Alfresco Community 4.2.e with CIFS configured on a RedHat server.

Hereunder, my CIFS configuration:

authentication.chain=alfrescoNtlm1:alfrescoNtlm
#
# URL Generation Parameters (The ${localname} token is replaced by the local server name)
#————-
#alfresco.context=alfresco
#alfresco.host=${localname}
#alfresco.port=8080
#alfresco.protocol=http
#
#share.context=share
#share.host=${localname}
#share.port=8080
#share.protocol=http

cifs.enabled=true
ftp.enabled=false
cifs.serverName=alfresco
cifs.hostannounce=true
imap.server.enabled=false
cifs.tcpipSMB.port=1445
cifs.netBIOSSMB.namePort=1137
cifs.netBIOSSMB.datagramPort=1138
cifs.netBIOSSMB.sessionPort=1139
cifs.broadcast=255.255.255.0
cifs.bindto=192.168.1.1
cifs.domain=xxx
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

After some times, the CIFS access from Windows machines becomes very slow and I have to restart Alfresco in order to work as usual.

What could be the problem ?

Thanks,

If a reboot "fixes" the problem then it sounds like a resource leak somewhere.   

Next step is to use a profiling tool to narrow down what the problem is.

Thanks for your fast response mrogers.

Do you have some example of profiling tool or some tips for this kind of issues ?

[mrogers]

At alfresco we use yourkit.   I've also used jProfile in the past.

I know there are several folks that benchmark and test CIFS so I'd not expect a slow down problem.   However clearly you have an issue.

May also be worth experimenting with the memory settings for alfresco to see if that has an effect.

Many thanks !

Have a nice day.
