% But speed can differ a bit per compilation (upto .5 seconds maybe due to how
% compiled code is organized which might influence caching. Who knows ... (or
% cares). For instance at 20200407 I measured 10.9 seconds after some new low level
% metapost magic was added but who knows if that was the reason, because mp
% processing is already fast. A week later, at 20200415, a by then 254 page file
% took 10.5 seconds, that is, we were at exactly 24 pages per second but after
% switching to gcc9 it dropped again. In december 2020, with IPO enabled I crossed
% the 26 pps barrier and went below 10 seconds but that was also after some further
% cleanup in \LMTX. Mid August 2021 I measured over 30 pps but not all is due to
% the engine I guess. End august we were are over 31 pps so it's not getting worse.
% (This means that on a modern desktop we probably can get around 100 pps on a
% manual like this but, always using laptops, I don't have access to machines like
% that. A modern laptop probably could perform over 50 pps.)

% Thanks to sebastian.miele@gmail.com for close reading the manual and sending

% On the 2018 Dell 7520 Precission Xeon laptop runtime for 322 pages is now exactly
% 8 seconds (just below 40 pages per second), we talking July 16, 2022.
%
% At the first of August 2022 the (slightly reorganized and updated) manual counted
% 350 pages and took 8.6 seconds to process (some 41 pages per second), so we're
% rather stable. End of 2022 processing that amount of pages dropped somewhat
% (occasionally under 8.3 seconds for 356 pages with little other system load). In
% means that 43 pages per seconds is now the new normal but that might of course
% become less again as we evolve.
% End Feburari 2023 I observed 8.2 seconds for 360 pages and making a format needed
% 1.9 seconds instead if the usual 2.1 but that can be a side effect of the terminal
% because the amount of output which is sensitive for refresh delays set. The new
% target is now 50 pages per second for this manual but on this laptop that is
% unlikely to happen any time soon. With tabulateusesize and tabulatesparseskips
% experiments enabled we needed 8.1 second and 44.3 pps.
