[quote=“gwhitfield, post: 36037, member: 344”]I know it’s an old thread but I’ve looked at others and didn’t get any closer to an accurate description of the problem we’re struggling with and now may have solved for ourselves.
We have server (A) FOG 1.2 on Ubuntu 14.0.4.1 hosted by vCenter Server 5.5.0. 2CPU/4GB RAM/e1000 NIC/SCSI drive. With PIG_Z_COMP set at 3, upload speeds were no better that 500MB/min while download speeds were in the 3GB/min range. After much googles I find some references to VMWare driver issues solved by command line “(sudo) ethtool -K eth0 tso off gso off” which worked. Upload went to 4.5GB/min on 1Gb connection, download went to 5.1GB/min without a restart of FOG server. There’s also an rx-checksumming edit suggested but we didn’t implement it to get to the speeds we’re at now. Maybe we can live without it.
Funny, we have another server (B) FOG 1.2/Ubuntu 14.0.4.1 VM 2CPU/4GB RAM/e1000 NIC/SCSI drive on ESXi 5.1 that required no changes to achieve 4.3GB/min uploads on 1Gb connection.
Now to get handle on how to make this change stick after a restart, something in /etc/network/interfaces but nothing worked yet, maybe a syntax thing idk. Also trying to get mysql service starting at the right time to avoid the Database Schema issue on restart. I know it’s in here somewhere, just haven’t found it yet. When I do I’ll try to update this.[/quote]
I’ve add the ethtool -K eth0 tso off gso off command to the S99fog scripts so this should be on your systems as well. I don’t know if we should add this to the installer though, as the interface is subject to be changed.
Maybe we can get a wiki entry explaining this?
