paket has been churning away on an update for over an hour now and is not complete. It has been hovering at about 26% CPU. The exploring lines are slowly being printed by the minute. What can be done to improve performance?

Wow that's really bad perf. I wonder why CPU is used at all. Usually bad
perf is a result of the slow nuget api, but this would be seen as CPU be
basically idle. So it seems something else is going on. Can you give me a
chance to profile this?

Regarding "exploring". It basically means that we have to look at the next
version of a package since the last one doesn't fit the version
restrictions. So if you see paket exploring a lot of different versions of
the same package it basically means that you (or packages you use) defined
very narrow version restrictions to that package.

I cloned this repo and did a couple of performance wizard runs on it. The first one for CPU usage.

Being that performance gets slower as it goes when I run it, it feels like a memory issues. I ran the memory performance wizard too, but the analysis process is taking a while to churn through an 8 GB log file. I'll report back when I get it.

The memory performance wizard brings up the same code.

After a quick look I think there are two things that produce this strange
behavior.

  1. there is a issue with the prerelease version requirement for xunit.
    Somehow the fscheck.xunit dependency to xunit conflicts. I think the
    resolver is too strict about that and that's why it tries out all
    combinations.

  2. a memory issue seems to be in the code which needs to be analyzed
    further

Why are all the FSharpx.Collections being explored? Without prerelease on xunit it doesn't explore them all, just the one.

May be prerelease here is causing some sort of recursion problem.

As I wrote above it's detecting a conflict between prerelease requirement
and non-prerelease requirement. This is too strict and I'm going to fix it
this weekend.

Quick question in order to tackle part 2) of this. What profiler tools do you use?

Could look at the use of nessos stream library, which has some large performance gains over seq operations. Not sure about set though.

The memory performance wizard brings up the same code.

Ok I released a hotfix which should relax the prerelease requirements. Please check if this works for you.

I will still keep this issue open since I really want to analyze the memory issue.

Regarding streams: I started with lists, then went over to sets since I needed uniqueness. Then I changed the order in the set. So in the I think we need a priority queue for the open dependencies and a set for the closed dependencies.

Yeah - I am thinking more "streams rather than lots of chained Seq. operations" than replacements for Set operations.

I used the profiler that comes with Visual Studio 2013 Ultimate. Select Analyze > Performance and Diagnostis > Performance Wizard.

it looks like we are no longer tail recursive. I will try to fix that.

Did the quickfix help?
