Troubleshooting / Re: TXP-X : How To Verify?

« on: September 09, 2018, 11:13:07 PM »

I've got iPerf3 running on the test machines themselves, transiting the Wanos instances.  Tomorrow I will change the dedup level and see what that brings.  FWIW while I am running in bridge mode the entire setup is on a single subnet (two Wanos instances, each with two NICs, one NIC in the "local" LAN Segment with the test machine, one in the DMZ/WAN LAN Segment).  Traffic is most definitely transiting the Wanos instances as if I power either of them off the clients can't even ping each other.  I saw the warning in the docs about TCP-X and routing but I think I don't think my setup meets the conditions that were cautioned against.

Thanks for the suggested test, I did what you'd indicated and got 2.2MB/sec...roughly 17.6Mb/sec on a 20Mb/sec link.  That seems reasonable.  I also did a few other tests...

• iPerf3 - optimized and accelerated I hit 103Mbps on the LAN Tx, optimized to 8.4Mbps on the WAN Tx.
• iPerf3 - accelerated only (showing pass-through) I saw 19.9Mbps on the WAN Tx.
• My application (DICOM) - optimized and accelerated I hit 8.6Mbps on LAN Tx, optimized to 2.2Mbps on WAN Tx.
• My application (DICOM) - accelerated only (indicating pass-through) I saw 10.7Mbps WAN Tx.

I'm mystified here...curious about why the WAN link isn't being more fully utilized when optimization is in effect.  FWIW right now this lab is all in place on a single VMware host...no traffic is actually hitting the wire.  All VMs are over-provisioned (ex. the Wanos VMs are 4 vCPUs and 8GB RAM) and the host has plenty of unallocated resources, this isn't an issue of CPU, RAM or network contention.  Is it possible the protocol in use (DICOM) is not well-suited to optimization/acceleration?

Troubleshooting / TXP-X : How To Verify?

I’m running a trial of 4.2.3 and I can see my traffic is being optimized (cool!). I have now enabled TCP-X (TCP Acceleration) and nothing appears to have changed/improved performance-wise. My link has ~40ms (20 Mbps link) latency and without acceleration I’m hitting ~2.7Mbps throughput. With acceleration enabled I’ve actually dropped a bit down to ~2.4Mbps. Is there any way to confirm that traffic is being accelerated? FWIW this is on a single subnet and the Wanos instances are in bridge mode. No routes added, the optimization rule (working) is set up for the subnet and I just have the default “accelerate everything” rule in for TCP-X.

Thanks!
