Byond will queue all browse(), browse_rsc(), and winset() calls to the client, to ensure they load in order, and ensure any resources from a browse_rsc call (css/html/js) are already at the client by the time any html windows loads. How ever, each file is processed separately, and byond will wait for the reply from the client before it will send the next file. Our current system sends all of these html resource files to the client at once when they connect, this is the sole cause of the lag when a client connects. Byond will not send the client a file it already has, but it has to ask the client first, and it does so one file at a time, waiting for a reply from the client before sending the next one down the pipe. This system fixes that. Basically it works like this: Client connects: nothing happens, no massive queuing of browse_rsc() calls, so no interface delay Client opens a asset_cache controlled html based interface Asset cache gets notified by the html based interface what assets the client needs to have. Asset cache checks to see if it's sent that client those files. Asset cache sends the missing ones, adding them to the list of assets the client has. This basically spreads out the delay to when you first open a window that uses resources, where it is much more manageable. I've kinda done a halfass port without too much thought, I see some room for improvement to better fit /tg/'s coding style and make the system more flexible. I'm PRing this because if I don't, it will never get finished. PDAs and html_interface has been imported in to the new system lazily to test. at 100ms connection start interface lag went from 35 seconds to 16 seconds. Nanoui hasn't been imported, and once it is, that should drop down to almost nothing. I'll work on this some more after some sleep.
