Guys, i use opera on a Lenono Thinkstation D20 production workstation, fully maxed out hardware spec, newest bios, with 2 Xeon X5690 processors, offering total 12 cores 6 high end cores per CPU, 24 treads 2 treads per core, 96 gb triple channel RAM and P2200 Nvidia Quadro hardware running in compute and display mode to accelerate editing, managed by Windows for workstations. I also feel frequent issues with it of this beefy hardware. My hardware is not fast but it is optimized to take heavy workloads without taking much performance penalties. Something is obviously wrong with Opera. Sad, i had so much faith and belief in the browser. I also feel slowness and lagging in browsing hanging and not loading webpage assets.

for the curious, the beast as we call it here is primarily used for audio recording and audio editing, and time to time used for browse in between recording and editing sessions

Re:
This is a follow-up of the High CPU/RAM/ETC Usage Topic

I really have issues with Opera misbehaving and not being able to manage resources. And i use much beefier hardware, i use Lenovo Thinkstsion D20 workstation, with the full load of 96 gb in tripple channel mode, 5520/58 chipset with ICH10R system controller, dual Xeon X5690 cpus, in total of 2 cpu's, 6 cores per cpu, 2 treads per core and quadro p2200 in compute/ display for further accelerstion, os of choice is Windows 10 pri for Workstations, with full natice support for this grade of hardware and its fearures, and proper drivers setup. There are times when my ws freezes with opera. It happens with opera only. I use⁶is quite a beefy hardware, lot of cores, fast cires made to take sustained heaby duty loads, and instill feel resources are managed suboptimal. An update with screeshots will follow up later today.
No such issues with chrome. Chrome is fast, snappy, responsive. Please Opera, reevalutate your code. This is not a core 2 duo laptop i work with. It is professional grade hardware designed and meant to take and manage huge workloads.
