Hi!
Here you have the first one.
Case no 1. Old PI/133MHz laptop
This old laptop is working quite well on net on a DSL-line, but of course somehow slowly, but it doesn’t matter too much on that particular “light” usage of it.
I have been testing it hundreds of times on PC Pitstop www.pcpitstop.com, and got all the time much varying test results between sub-sequent re-boots. Sometimes the throughput results MIPS, MB/s, MP/s etc. are very good on all the CPU, memory and video, and remain about the same on sub-sequent tests during the same boot. But after a re-boot, warm or cold or cold-cold-cold, the results are always on a completely different levels compared with the previous test rounds, sometimes really bad, sometimes medium-good/bad, sometimes there between etc. Also some of the result values may vary between sub-sequent tests during a same boot, but this isn’t so much remarkable. But, sometimes I have been notising, that if e.g. CPU and memory are getting good values/speeds, the video may get a lower one, and if e.g video is on full speed CPU or memory may have a lower speed, and this same applies between all these 3 components somehow randomly … And sometimes all the three may get quite low results at the same time.
So, what might be behind all this? I have been thinking about it and come to the conclusion, that there must be some “rules” how the mobo/bus resources are given or divided to the components at the boot-up beginning. And, I have been doing the tests now so many times with a certain procedure/routine and with just the same few selected programs/processes on, so, there can’t anymore be any varying influence from that direction.
If anyone is interested on this case I can give more detailed descriptions and test details/values.
Best regards,
Pete V.
