[Therion] Therion runtime cmd window (+ th2 display) lag on compile with Windows 11

Sorry to hear your speed issues are even worse than mine.  I got a fast device mainly to reduce lag with Therion and opening the exported pdfs.  Not so much because Therion was slow but because it is where I spend my most precious discretionary screen time.  Other than the start-lag issue, comparison of my old and new therion.log files showed a typically 2 – 5 times speed increase.

> For me there is a 6 seconds lag to open the cmd window, but also a 6 seconds lag at the end when the cmd window is closed and Xtherion reads the output to display it in its interface.  

At least I only have the lag at the start of the process.  The transition from cmd window to XTherion for me is instantaneous.  Although I recall on rare occasions an inordinately long end-lag, probably back with Windows 10.  Maybe the content of the project that has just been compiled impacts on that?

> However, my main problem is the huge delay (which can be of several minutes) for xtherion to display a large th2 file : it takes 75 seconds to display a th2 of 2500 lines of text (that is 538 commands). During that time, xtherion says "Processing commands ..."

That is a disaster.  I just checked a 3500 line th2 file, the largest I could quickly find.  It takes 6 s to complete the entire opening process (‘opening image’ - which are 5 large PocketTopo xvi files and ‘processing commands’).  Moving an object to another scrap is about 1-2 s.

So broadly, except maybe in Yann’s case, is it that Windows 11 has added delays (more, or less, extreme depending on user) to Therion that were not present with Windows 10?

I have always thought of Therion as placing minimal load on a device.  Has anyone come up with minimum, recommended and optimum processor, graphics and ram parameters (other than more is better)?
