Build 594 - someone forgot the accelerator !

Hi Guys,

sorry it's been hectic, so I have only just got to play with latest build. first thing I noticed ... it's ...... s l o w .

prior to this build it would take approx 2mins to open my app (as shown on one of our sessions), now it is taking nearly FIVE minutes. that is a huge difference.

any suggestions ?

    Hi,

    I've taken a look through our source control logs and I think there's only one change that could impact performance. The previous builds would not instrument functions with more than 30,000 lines in them: we've increased the limit to 300,000 lines.

    In general this means very large designer-generated files: these also happen to produce a lot of instrumentation so the effect could be quite large in some cases. Could you check to see if you have any of these files?

    This could be something we make optional, as quite often the results produced for these functions aren't very enlightening, so being able to disable them in cases where they are dragging performance down could be useful.

    You could also check task manager as your application is starting: having something else loading the CPU at the same time can cause quite a substantial difference in times - because profiling is quite CPU-intensive, the effect can be quite marked.

    PUBLIC APOLOGY
    ============

    Hi Guys, I had a look at the CPU, nothing special happening, even though the laptop runs a SQL Server instance, it was behaving, and nothing really had changed from previous tests. The code size would not exceed 30k lines in any one file, so I don't see that that would be the issue.

    HOWEVER, I did find something really interesting...
    when I disabled CA-Anti Virus, I get an execution time of just over 1 minute ! so I re-enabled, ran test again, 5 minutes, snoozed, under 1 minute.

    So the issue is actually the AV software playing havoc with performance (although nothing showing on perf charts, mem usage all good at that stage etc), hence the public apology, I had assumed that the issue was RG problem, that is not the case. In fact, when disabling the AV, Ants 4 is having hardly any effect on speed.

    so for now, I will simply snooze my AV when running the tests.

    Thanks for your feedback.
