No progress when large number of downloads added to queue

[ptr727]

Hi

When I add many downloads to the queue, more than about 50, sabnzbd makes no progress, and the API and web UI often time out.
From the logs there is lots of continuous download activity on all the added nzb's, but no real progress.

If I shut down, restart, then quickly delete all the items, sabnzbd becomes responsive again.
If I add files two at a time, they complete fine.

I am running from GIT master source on Windows.
I have 3 news servers with 8 SSL connections each.
I have flags set to pause while processing.

Is there a flag that will make sabnzbd process just one NZB at a time, instead of trying to get size and parts from all the NZB's in the queue?
Any other advice please?

I followed some google troubleshooting, and noticed that my yEnc was not the C version, explains some of the slowness.
I am positive it used to be present and working, maybe a GIT update at one point nuked it.

I am now running 0.7.20 from the binary Windows installer, and it is flying.

The yEnc module has to be installed separately in the installed Python.
On Windows, that requires an old Visual Studio compiler and a lot of tweaking.
Neither the binary or the source of yEnc are part of our githib repository.
