Hi All.

 

I’m doing some troubleshooting around restore speeds that are slow.

I’m wondering what the [AllocBuf Speed] is covering in the cvd.log?

 

Below is copied from the cvd.log

6457 7993 04/18 12:17:13 19188780 [FSRESTHEAD ] 18-# Stats: [AllocBuf Speed] Curr Avg [1754.47] MB/Sec, Bytes [54561966768]; Total Avg [184.61] MB/Sec, Bytes [1039473982296]

 

And a side question.

The [Head Network] and the [Tail Network], is that covering the network transfer speed?

Appreciate if anyone could enlighten me.

Hello @ApK 

Buffer Allocation is the speed at which the OS is allocating a slice of memory for the operation. I’ve never really used the Head\Tail network statistics so I cannot say.

When a stream completes we log details performance metrics in CvPerfMgr.log on the MediaAgent. This will give a clearer breakdown of the performance of each operation.

 

Thank you,

Collin

This was a MSSQL restore.
