It was a hiccup on the server side. Sorry about that. Should be back to normal now.

Things are OK on the server side. Ah, scratch that. I see the issue!... Check now?

You can't get "Read X bytes since last reboot" from the standard performance counters, so, no, Resource Monitor doesn't have this data. The best it can do is the IO rate at one-second resolution.

Interesting idea, thanks. I'll give it a try.

Basic window with stuff drawn on it with GDI and GDI+ in a double-buffered way. Edit: Scratch the GDI+ bit, it's just GDI.

Thanks, glad you like it!

Ha. Good question, actually. The simplest option would obviously be to just show a conventional candlestick when zoomed out. There might be an option to do something interesting with rendering the stick when min/max have the same highe

> How would you extend it to allow zooming on the Y-axis? Well, the whole point is to NOT need to do any Y-scaling. What would be the case for zooming in?

I am very much tempted to somehow shovel it in, but I don't think it belongs there. Perhaps only if as an Easter egg.

I see no point in that. It's trivial to do in several hours from scratch.

As I said in another comment, the interesting part that I wanted to share is how the data is graphed, and not that there's an executable.

Zero plans, sorry. This is an internal tool that just happens to produce good looking graphs, so we released a build to let people play with it if they want to. It's not a beta of a product, more of a tech demo... if even that.

Yep, noted. We are a desktop software shop, so mobile browser support hasn't been a top priority.

Author here. We had a need for a tool to graph IO activity at arbitrary sampling rates, so there was finally a solid excuse to do some datavis work :) The thing I wanted to show is not the program itself, but the idea of factoring values an

We've been using a variation of this for the "customer dashboard" part of the website (we make desktop software). The login page defaults to "email me a login link", but once they get in, the customer is given an op

Keep in mind that this paper was outdated the moment it was published and announced on p2p-hackers mailing list [1]. It doesn't deal with the "long tail" of NAT devices that increment/decrement ports in (somewhat) predic

It is symmetrical, but there are nuances. If A closes or errors out, the proxy should first push out any pending data and only then close B. The same goes for when A sends a FIN - it should flush any data queued at application level befor

Yep, it works with anything that is addressable as a file system location, i.e. as X:\Path or \\Server\Share\Path format.

Short of enabling jumbo frames on network adapters I don't think there's much in terms of system-wide tuning. Every program that cares about IO performance would implement it on top of raw File API (CreateFile, ReadFile, etc), so

For one, you can get an idea if you are getting proper performance out of your devices. For example, NVMe drives plugged directly into certain revisions of ASYS motherboards will not get to their spec speeds, you will need to use a M2/

Just a very pedantic IO test that goes through a long list of permutations of IO buffer sizes, counts and IO modes and finds the one that delivers the highest read/write rate. Basically, it estimates maximum IO rates realistically ac

At the risk of stating the obvious - tracing in itself is not that useful, unless you are after just the aggregated stats. To use traces for reversing the API/IOCTLs, it's equally (if not more) important to have a good UI for filt
