Several of these errors show up and videos from the share load slow--about 30 seconds delay.

I've kinda pegged it to network interruptions. On the other hand a problem like this happened with a mysql site where pages would load similarly slow and that solution was adding TCP_NODELAY to the mysql config file.

Now, I've added

to /etc/samba/smb.conf to no effect and this cifs guide says cifs doesn't even look at smb.conf. This is a client cifs mounting a Windows share.

Would there be some place else to add socket options? In /proc or the fstab file? I've looked and hadn't found it yet.

Thanks.

It looks like there is no way to add socket options manually or by fstab for cifs client.

The fix for our slow site wasn't TCP_NODELAY in the MySQL my.cnf file, it was:
[mysqld]
