Misto !
Microsoft: " The company has warned the Jan. 3 patch may cause compatibility problems with some anti-virus applications that make unsupported calls into Windows kernel memory. These calls may cause stop (blue screen) errors) that will stop a PC or server from booting. “To help prevent stop errors caused by incompatible anti-virus applications, Microsoft is only offering the Windows security updates released on January 3, 2018 to devices running anti-virus software from partners who have confirmed their software is compatible with the January 2018 Windows operating system security update,” it says.

Vezi ca am pus un link dimineata, e vorba si de scaderi cu 60% in unele teste de browsing. Nu e chiar caz real, de utilizator obisnuit care intra pe un forum sau pe iutub, dar impactul de performanta e maricel! Memoria nu vad sa fie accesata prea tare in Vegas, mai mult procesorul si eventual placa video ar conta. http://openbenchmark...-AL-KPTIKERNE72 Cred ca trebuie sa se mai linisteasca putin apele si sa vedem benchmark-uri din surse ceva mai serioase si pe mai multe generatii si modele de CPU-uri. |

Astea sunt ?
2018-01 Cumulative Update for Windows 10 Version 1703 for x64-based Systems (KB4056891) Vad ca deja mi le-a bagat pe gat M$ Voiam sa bag o sesiune de Warthunder si tocmai ce am primit un ecran albastru: ceva legat de memory management. Nu am avut telefonul langa mine, sa-i trag o poza repede. http://news.softpedi...03-519219.shtml Deja am ecrane albastre. LE2: Dau drumul la joc, porneste -intru in misiune. Bag un Alt+TAB sa dau drumul si la Fraps gandidu-ma la minusurile de performanta. ZBANG ! ECRAN ALBASTRU ! Va dati seama daca eu ca home user am asemenea probleme, dar cand vine vorba de servere ?! Ma gandesc salariul asta sa imi iau AMD Ryzen. Deci nu se poate asa ceva ! Si cica e ceva...minor. Attached FilesEdited by Dany_Darke, 06 January 2018 - 08:37. |

Da dar nu pentru a scoate update-uri deja instalate...

In short-run own benchmarks ComputerBase was on a notebook with Intel Core i7-4600U in spontaneously running simple benchmarks of the Phoronix Test Suite no beyond the measurement inaccuracy performance determined (tested were pts / blake2, pts / build-linux-kernel, pts / openssl , pts / phpbench, pts / pybench and pts / sqlite). In the tweet mentioned in this news benchmark “time du -s -x /” (So the totaling of the size of all files on the main file system) but we could also notice a significant performance dip: Without PTI, the command delivered in 0.64 seconds Result, with PTI only after 0.82 seconds, which corresponds to a performance penalty of 28%. However, this “benchmark” is to be described as a worst-case, because it consists almost only consists of performing in a loop for each file the “stat” -Syscall. The widely used PostgreSQL database is running at around 7 percent slower with a PTI benchmark. Linus Torvalds described this performance loss in an answer as “in line with expectations” but of course highly dependent on the actual workload. Meanwhile, there are further PTI benchmarks on Phoronix, which indicate dramatic factor 2 and higher slumps in synthetic file system benchmarks on NVMe SSDs, significant differences in the lower two-digit percentage range for PostgreSQL and Redis databases, and no measurable differences in Encoding benchmarks like FFMpeg and x264 as well as kernel compilation. ComputerBase gaming-savvy readers will be pleased to note that there is no measurable performance degradation in Phoronix’s game benchmarks, so gamers can probably lean back and relax, at least assuming that the results of the Linux benchmarks are transferable to Windows you should go out first. As it currently looks like at best the charging times could be negatively influenced by PTI. |
