This is why I am waiting for the Xorg modular tree to come out (soon, soon, Real Soon Now they say). Once I have that I can start to classify the modules into optional, needed, and needed later categories. It's a lot more work doing that to the current monolithic X. Once classified, I will then know what to start now, what to start in parallel after starting entranced, what to leave out completely, and what to hack for speed. > hmm - i still think you have some gross disk IO issues. i may have > only a fraction - but e starts in like < 1 second for me (200 not > 1600, but i dont get like a 20 / 8 (2.something) second extra lag. > what fs are u using? ext2? ext3? xfs? reiser? what disk? whats its IO > capacity? (hpardm -t /dev/device) ? ext3. As part of my "what can boot faster" work I did some timing tests. Others where faster at writing, but booting is more read bound, and ext3 won the boot race. Xfs was a close second, and I would recommend it for multimedia work, since it gave more consistent times, and it was designed for multimedia work. Reiser and JFS where both much slower, but again there was not much difference between the two. I have not tried Reiser 4 yet. I also only tried journalling file systems, so ext2 was not part of the tests. cluster:/home/dvs1 # hdparm -t /dev/hda /dev/hda: Timing buffered disk reads: 148 MB in 3.01 seconds = 49.19 MB/sec Are you reading in all of the eap at start up? For some strange reason most of the e17genmenu generated eaps are around 92KB. On the other hand, I put off a new HD purchase to buy my wireless modem, so space is tight. Thousands of eaps may have got scattered all over the disk. E17 startup with thousands of eaps may be seek bound on my computer. > btw - partt way through. my 200 eap's use about 6mb of disk. the cache > file for that dir is a touch under 7kb. thats all e has to load on > startup - so it should be massively faster for you in the future. i'm > still workign on it and its not enabled in production code yet. :) Let me know when I can try it out. > > Oh well, back to struggling to get a cvs update of e17 out of > > sourceforge.

It's propietry wireless broadband that is more like mobile phones than current WiFi. I don't have to worry about finding a hot spot, as it works anywhere in the city. Australia is a small continent with most of the population hugging the coast, and very large expanses of nothing in the middle. Things like mobile phones and iBurst are not likely to work 50 kms away from the coast. iBurst is new, so it doesn't yet have the same coverage as mobiles, but they are working on it. On the plus side, an iBurst tower has greater range than a GSM tower, so they will need less of them. Getting decent telecommunications outside the main cities is a big political bun fight at the moment. My Internet access is the equivilent of ADSL, but without the telephone line, or any other wires. It even works while on the move, but since I have a desktop, I would still need to plug into a power socket. Laptop users can use it while driving on the freeways, and I could probably use it on the City Cat ferries, catamerans that are part of the public transport system in this city. If only they would let me use their power. B-( At any rate, the really slow cvs was not due to limited bandwidth at my end, as it spent most of that five hours just siting there doing nothing. The e17 network monitor said "0B" for most of that time, unless I was doing other net stuff. SourceForge sometimes has major performance problems, and when they do they often give priority to account holders over anonymous cvs, and they may even give priority to paid subscribers, I wouldn't know, I'm not a paid subscriber. I don't have cvs access to enlightenment from my SourceForge account, so when updating e17 I get the anonymous priority. But I should get better for my own projects, where I can get account priority. -- Stuff I have no control over could be added after this line.
