In comparison, iStat menus have different pages for the various use cases and hardware and don’t club everything on a single page of the screen.īoth have functions that help you monitor: It also shows you all the processes under a single tab and can help you terminate the misbehaving process that takes up a massive amount of resources. This can get a little confusing for the regular user, but it is excellent at maintaining all records from a single page. IStatistica, on the other hand, takes a simple approach and brings all the details on a single page. However, it doesn’t just stop there as it also has detailed graphs for processes and other hardware components such as CPU, GPU and Memory that helps you keep track of all performance hits and the load on each of these components separately. IStat Menus has a detailed set of pages that shows you all the apps running in the background and the foreground. iStat Menus vs iStatistica Pro: common featuresīoth the tools iStat Menus and iStatistica Pro come with some standard features that make them a great system monitor application. Go for iStatistica Pro if you want a simple no compromise activity monitor app at an affordable price tag. Go for iStat Menus if you want all the benefits that a professional ready activity monitor tool provides. Here’s how the two acitivity monitors stack up in 2021. Since these two apps are at the top of their field in the macOS monitoring this year, the best way to do a comparison and pick the right one for you is to slice up their performance and price. Unfortunately, the process of identifying the connection to which a packet belongs is part of the dissection process, so this might involve handing packets from one thread to another.Īs for memory, saving the full results of dissection if you have enough physical memory (and perhaps discarding it if the system is reporting memory pressure to the application macOS has mechanisms to do that, other OSes might or might not) might speed up filtering, but so might reducing the amount of dissection done to evaluate a filter.If you’re after the very best Mac system monitors, this is a question you’ve likely asked yourself: which is better in a match-up of iStat Menus vs iStatistica Pro? assigning packets to CPUs based on transport-layer connections to reduce the chances that two packets being dissected in parallel will have dependencies that force dissection of the later packet to stall until dissection of the earlier packet completes, as well as adding dependency checking to stall in the case that there is a dependency between packets from different connections. We've thought some about ways to try to parallelize it, e.g. It is not currently parallelized, so it only uses one CPU, and only one of your CPUs could be pinned by the process, so it may not get much above 12.5% of the system's total CPU power. Packet dissection is a process that is hard to parallelize so that it can use more than one thread the dissection of packet N is not necessarily independent of the dissection of packet M, for M < N. I was hoping that's the kind of operation that could "pin" the CPU.Īs a multiprocessor system, your iMac has 8 CPUs.
