Re: Slow Apt



Out of curiosity, how does "top" look when it's running? Especially things like "wa" (IOWait) and "st" (steal)?

First, hello.  New to the list, but I've been using Xen Hypervisor for a
long time.

I'm curious if anyone else has had this issue.

I recently upgraded a server from Debian Squeeze to Buster with kernel
4.19.0-16-amd64 and found that apt/aptitude commands are slow in response.

For example, 'apt-get update' can take 10 minutes to complete, hanging
up on certain parts of the downloads either at 0% or 90%.    This is
something that normally takes a few seconds.

Even the DomU's suffer the same issue.


On another server I have kernel 4.19.0-14-amd64 and it seems to be
running just fine most of the time.  I do get some hiccups, but not
nearly as much as the above upgraded server.


I've also noticed that writes will sometimes pause for several seconds,
specially when transferring large files.


Setup:

E3-1230 V2 @ 3.30GHz

16 GB RAM

Hard drives are spinning disk.  2 TB drives (EXT4)

DomUs are using Disk.Img for their disk.
