doctorstupid2 Dirty Deeds Corp. Axiom Empire	Posted - 2007.01.01 11:21:00 - [121] Quite possibly a stupid question (hopefully the irony in that is not lost on anyone) When creating the junction to S:\cache, windows automatically names it "Link to cache," does it need to be renamed to just "cache?"
marioman Caldari Eye of God	Posted - 2007.01.01 11:22:00 - [122] I've tried all of these and none work for WinXP x64. Anyone know of one that does?

Teluy Caldari Hadean Drive Yards	Posted - 2007.01.01 12:50:00 - [125] Guys, why don't you leave the caching to the application? Or to the filesystem? Heavily accessed files usually are kept dynamically in filesystem cache anyway and I guess eve itself keeps a lot of stuff in the cache as well (textures, etc.). So I guess you are ending up having a lot of things twice in the memory - that's no problem for people with a lot of memory, but might actually worse the problem for the ones with < 1GB ram. Just my two cents.

Just my two cents. Because the filesystem cache is of a limited size and you can't control it. The filesystem cache will end up being filled with the STUFF files from EVE's data and a little bit of the cache folder, not all of it. -[23] Member- Listen to EVE-Trance Radio!

The filesystem cache will end up being filled with the STUFF files from EVE's data and a little bit of the cache folder, not all of it. Good point, still the fs cache should cache the stuff which is mostly used, so it kinda adapts to the current situation. I don't know much about NTFS/FAT, it might be, that eve has some troubles looking up files (thousands of files in a directory). And the 'app caches by itself already' is still true. It just sounds wrong to me to manually cache :) - especially as it isn't really clear what the real bottleneck is (aka premature optimisation). Well anyway, with enough memory it shouldn't hurt (despite having a slightly more complex setup) ..: ) Teluy

Xen Gin The Dragoons	Posted - 2007.01.01 14:59:00 - [130] I've got it all running, except when EVE runs, it gets to "Acquiring Bulk Data" and seems to hang, while drawing in processor cycles. Anyone know why?

Dark Shikari Caldari Imperium Technologies Firmus Ixion	Posted - 2007.01.01 15:05:00 - [131] Originally by: Xen Gin I've got it all running, except when EVE runs, it gets to "Acquiring Bulk Data" and seems to hang, while drawing in processor cycles. Anyone know why? That's because you deleted Machonet, which EVE will have to reload. Try to make sure in the future to not delete it unless you're having trouble with EVE (in which case its a good idea). It'll take the client 20 to 60 seconds to do this, usually. Its a one-time thing. -[23] Member- Listen to EVE-Trance Radio! (DSTrance channel ingame)

D'an Y'eal Dirty Deeds Corp. Axiom Empire	Posted - 2007.01.01 20:13:00 - [135] Originally by: Dominie Dirtch What about multiple accounts? :\ Running two accounts on one PC for instance. I've run the startup.bat then run each of the clients you want (opening and closing multiple times as you wish) and run the shutdown.bat when you are done eve-ing Works for me

Just my two cents. Because the filesystem cache is of a limited size and you can't control it. The filesystem cache will end up being filled with the STUFF files from EVE's data and a little bit of the cache folder, not all of it. No it isn't. The cache is dynamic. It's also not a filesystem cache for NTFS but is a file cache. As it happens all NTFS metadata is stored in files anyway so the effect is similar. By being file based the cache is free to store information in whatever way is most helpful to the OS rather than just caching disk blocks. An example of this is compressed files. These are decompressed into the cache and stored that way. This avoids decompressing data more than once. It also means that for highly compressible data the CPU time spent decompressing the data might more than offset the time needed to read the uncompressed data from disk. I'm not sure about FAT but that's probably a cruder, traditional, block based cache. Having made that correction, however, I would agree that a RAM drive (if you have enough RAM spare) should help. -- (Battle hardened industrialist) [Brackley, UK] Linux is only free if your time is worthless

I don't know much about NTFS/FAT, it might be, that eve has some troubles looking up files (thousands of files in a directory). FAT certainly does because it has to perform a linear search of an unsorted list. NTFS OTOH is a modern file system and has B-Tree indexes. A directory has to contain many tens of thousands of files before there is a significant (in general disk bound I/O terms) drop in performance in locating an existing file. OTOH creating new files in a directory carries a significant penalty with B-Trees. Luckily most applications do more reading of existing files than creating. -- (Battle hardened industrialist) [Brackley, UK] Linux is only free if your time is worthless

chrisreeves Gallente Asgard Protectorate	Posted - 2007.01.01 21:53:00 - [139] Is it possible to link in the main post to any other of the free ramdrive proggy's that are mentioned in this thread?
Roemy Schneider BINFORD	Posted - 2007.01.01 22:31:00 - [140] reminds me... why the complicated path jumping...? the virtual folder is there already ^^

Can you point me to one in particular that can do more than 64MB? By the way, the evaluation version on the website I originally linked to has a "nag" that can be really easily disabled by going to control panel/start menu and taskbar/customize -[23] Member- Listen to EVE-Trance Radio!

It works for me on my XP Client so far.
Abbadon Caldari Pukin' Dogs Confederation of Independent Corporations	Posted - 2007.01.02 02:20:00 - [143] Just thought I would post a further update after playing with this for a couple of days now: I've used this ramdrive (32 and 64bit versions available) Linkage Its not free but I think its worth the cashola. Ive created 3 ramdrives and have mounted CACHE, CAPTURE and BIN directories. Ive used the batch files/tools supplied in this thread (thanks all) Result: Ive noticed a marked improvement with any session changes (instant screen load), and no lag whatsoever when in combat and there are 100 combat msgs per second popping on screen. FYI: System spec, AMD 64 x 2 4800, 2Gig ram, 2 x 7900gtx @ 1920x1200 max quality in driver) . Dancers plz. o/ --Jorauk boogies-eris booty bounces - Corte

Its unlimited, with the catch that the program will nag you by throwing fake "fatal error" exceptions when using the RAMdrive. However, this can easily be eliminated--control panel/taskbar/customize and then "Always Hide" the fatal error, and it will never show again! I installed the Pro version and set it to 128MB, and mounted every single EVE directory in it (that is, cache, capture, bin, logs, etc) and set the batch files appropriate ly. Speed? Even better -[23] Member- Listen to EVE-Trance Radio! (DSTrance channel ingame)
Abbadon Caldari Pukin' Dogs Confederation of Independent Corporations	Posted - 2007.01.02 02:28:00 - [145] Yeah DS, I had a play with the Enterprise version but found that mountvol wouldn't recognise the ramdrive volumes. The ntfs link prog obviously fixes that but iirc is still limited to one ramdrive only? . Dancers plz. o/ --Jorauk boogies-eris booty bounces - Corte

The ntfs link prog obviously fixes that but iirc is still limited to one ramdrive only? As far as I know you can install as many instances of the program as you want. But why would you need multiple RAMdrives? You can put all the folders on one RAMdrive anyways, so multiple RAMdrives is silly. -[23] Member- Listen to EVE-Trance Radio! (DSTrance channel ingame)
Abbadon Caldari Pukin' Dogs Confederation of Independent Corporations	Posted - 2007.01.02 02:40:00 - [147] Well, the reason I use multiple ram drives is purely from playing around. I wanted to try one folder at a time to see if there was any noticable difference. Ive ordered another 2Gig of ram and am planning on putting whole Eve install in ramdrive and i have read that creating 2Gb ramdrives can be problematic so i may have to stick with 2-3 smaller ones .

However, there are many RAMDrive programs available that support sizes up to 64GB. -[23] Member- Listen to EVE-Trance Radio! (DSTrance channel ingame)
Abbadon Caldari Pukin' Dogs Confederation of Independent Corporations	Posted - 2007.01.02 02:53:00 - [149] Im sure the ramdisk I linked to does allow "nested" mount points which should allow me to create one for the Eve dir (stuff files and main exe) and then have another linked for Eve\sub dirs. Also with regard to ramdrives @ 2GB or greater, I believe the problem is more hardware/OS related than ramdisk s/w. . Dancers plz. o/ --Jorauk boogies-eris booty bounces - Corte
Ryysa North Face Force	Posted - 2007.01.02 03:07:00 - [150] Edited by: Ryysa on 02/01/2007 03:09:15 seems that a program which would analyze the ramdrive directiories for MODIFIED entry on files, and keep tabs on the current MODIFIED entries on your harddrive, then automatically updating them would be the way to go. Make a check every 5 minutes, that way you would have cache backups every 5 minutes, make an artificial write queue... It's really easy to do, too, and wouldn't cause much overhead, since you would only copy over the files that were modified (probably not that much). Also, i think the portraits aren't all that important, the only important ones are the small ones, which get loaded when you enter local, not the large ones when you do show info. So basically, what you want to do for optimal speedup/ram comparison is reroute all eve I/O WRITE calls to the ramdrive (pics/logs), put certain files on the ramdrive - machonet folder, small pictures/portraits. And slowly write new/modified files back to the hdd. There's only so much you can do of the last paragraph without very badly breaking the EULA... I'll poke around :) P.S. about the 64mb limited driver... that's 10 minutes of work in SoftICE, if even that, to remove the nagscreen and the limit... It is illegal though ;) All about target jamming
