Has anyone else noticed scripts being slower in 1.10?

I've been noticing that script performance seems to be sluggish these days, so today I finally went around to take a closer look.

I wrote this script that generates a "script performance score". It's nothing fancy, it just basically times the number of seconds it takes to count to 100.

In 1.9, the scores were generally:
0.04 seconds: Completely empty sim
0.4 seconds: Generally average sims
0.8 seconds: Starting to get sluggish
1.5+ seconds: omg the pain


CODE
default
{
    state_entry()
    {
        llSetObjectName( "Lag Timer" );
    }

    touch_start(integer total_number)
    {
        integer i;
        llResetTime();
        for ( i=0; i<100; i++ );
        llSay( 0, "Score: " + (string)llGetTime() );
    }
}


Today, floating around the grid, "average" scores seem to be around 0.8s, with a lot of sims in the 1.5+ range.

Sim crossings seem to be more unfriendly now too. Anyone else noticing anything similar?

I was playing around with "Top Scripts" in the estate debug menu today, and I noticed that one of my objects was taking up significant sim time (relatively speaking), even though it isn't doing anything.

I can't say I've noticed anything.

I've noticed poorer performance in scripts that use llSetPos and llSetRot, but I don't know if that's sim-dependent.

I agree on the most part, in fact my whole experience seems to be more sluggish, but that'll just be the updates, and me not updating my drivers in about 2 months.

Anyway, I got a score varying from 0.15 to 0.20.

A few results being repeated in a rather new friends sim:

0.200970
0.223358
0.178791
0.201074
0.156393

Just thought I'd give you some results to produce some sort of analysis if you felt like it.

Oh, that's a good point Iron - one thing I've noticed with the top scripts thing -

It used to be that objects with that only had non-active scripts (no timers, listens or sensors) wouldn't consume any CPU time unless they were specifically doing something.

Now it seems that all scripts consumed CPU time regardless of how whether they're doing anything or contain active elements.

While I'm here, does anyone know what the units "Top Scripts" means? The Lindens never answered my question:

It is supposed to be ms per frame
