Hi Mark, even with 16GB RAM I needed to install smtube to get a decent view of videos prior to your patches. Patched last night but only tonight I am able to do some testing:
At present I have openend - LibreOffice Writer with one doc - LibreOffice Calc with one doc - gimp with one picture - Pidgin-OTR - smplayer (nothing playing) - Thunderbird (two mail boxes) - Firefox with 10 tabs open, one of them being YT (Theo talking about pledge at Hackfest 2015) Even though YT is hanging every now an then it it now perfectly possible to watch / listen / follow the presentation although I have just a modest line. CPU usage (noticed via 'top') peaked at around 160% but average seems to be around 100%. I didn't notice any drawbacks from your patches. Every program is responsive, only thunderbird had some delays while typing this post (listening to Theo meanwhile). While this is not a "serious" test (by academic terms as it is not 100% repeatable) I can only report that I didn't come across any failures. Instead the system "feels" to be highly responsive with any task I tried. To summarize: THANK YOU! Best, STEFAN OpenBSD 5.9-beta (GENERIC.MP) #1863: Sun Jan 24 21:35:42 MST 2016 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 17082359808 (16291MB) avail mem = 16560455680 (15793MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.7 @ 0xeb500 (35 entries) bios0: vendor American Megatrends Inc. version "1.05.01" date 08/05/2015 bios0: Notebook W65_67SZ acpi0 at bios0: rev 2 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP APIC FPDT ASF!
