I don't particularly like system/network latencies. way back when, I was one of the people that did hardware mods to 3277. while 3270x were "fast" ... they were still half-duplex (and could have other processing issues). In "real" interactive paradigm ... it was possible to be typing concurrently with the screen being written; if you happen to hit a key while the 3270 screen was being written, the keyboard would lockup and have to be reset (there was FIFO box that could be inserted between the keyboard cable and where it plugged into the 3270 head, that was workaround to keyboard lockup). it was also possible to do some soldering inside keyboard case to adjust repeat delay and repeat rate (it was possible to adjust the repeat rate ... like for moving the cursor around the screen ... so it was faster than the screen refresh rate ... i.e. the cursor could continue moving after stopped pressing key ... took a little practice to get use to). and then there was big performance hit moving from (local channel attached) 3272 to (local channel attached) 3274s; old post with 30yr old data: http://www.garlic.com/~lynn/2001m.html#19 3270 protocol Using the 3272 and 3274 hardware service numbers and adding them to typical system service times for the end-user perceived response. hardware TSO 1sec. CMS .25sec. CMS .11sec. 3272/3277 .086 1.086 .336 .196 3274/3278 .530 1.530 .78 .64 ... snip ... there was somebody in the company claiming that they had the best internal vm/cms service with quarter second response ... I pointed out to them that I had service with .11sec response and still under quarter second when taking into account 3272/3277 processing (they were most unhappy). in any case, i have line-mode process that uses wget to retrieve pages from 70-80 news websites ... it then does diff on the previous retrieval and current retrieval and extracts any remaining URLs. It then double checks the URLs against the firefox SQLite file to see if the URL has been retrieved before. Previously unretrieved URLs are sent to firefox for retrieval in background tabs (there are some heuristics about time-delays between URLs for the same webserver). I then can browse thru 400-500 tabs w/o annoyance of network latency ... much more akin to turning pages in a newspaper. I've been doing this from just about the time of original tab introduction ... back when everything was flat files ... but had to adjust when move was made to SQLite. Note that firefox has significantly improved its efficiency of using storage ... but I still have to be careful about going over 100 tabs on a 1gbyte laptop. -- 40+yrs virtualization experience (since Jan68), online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
