Hi Everybody, my rails 1.2.5 application runs in a linux embedded environment with serious memory constraints. I would need to know how small a memory footprint I can hope to get. I run ligthtpd with only one dispatch and I did already remove actionmailer and actionwebservice which I do not need. Currently top shows a memory footprint of 720K for lighttpd and 25M for the dispatch.fcgi process. The smallest the footprint, the better so any suggestion on how...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 What is the expected footprint of a tool using the LLVM JIT? I have created a simple project that uses the LLVM C++ API to JIT calls to XPCOM method signature... it works well, but the component DLL is very large (Linux x86-74, 5.8MB optimized and stripped). Is this normal? Am I linking to "too much" or not using the...

We have a large bitcode file produced from a tool. It's about 23 meg. When we compile this with llc, the footprint is 4-7 gig depending on which target. On a desktop this is not such a problem but it is on mobile devices. The suspect is that the flow graph for the entire program is built and kept for the duration, even if no optimization needing it all is in progress. This would make us think that if we w...

...September of last year in school. I think I'm fairly competent(I Hope :) at it and we were recently discussing bloatware in class. Vorbis seems so large and complex that I offen get intimidated, so I was wondering if anyone else would like to possible work with me on reducing the memory footprint down from 500K? From what its described, that seems to be fairly large. I have a copy of Visual Studio, so I'm all set with tools. However I'm a newbie when it comes to working on large-code, open source stuff like this. If your interested, please e-mail me privetly, or on AOL IM (cardb...

Hey all, I have a potential project which calls for a very small form-factor computer like this: http://www.marvell.com/products/embedded_processors/developer/kirkwood/sheevaplug.jsp However, I am needing an FXS port integrated into a small footprint computer. Nothing larger than a WiFi router or gateway device, but the smaller the better, and able to run Asterisk with at least a spare USB port and preferably WiFi on the system (but no necessary). Even a device that could integrate the S100U into the case would be good. Anyone know of a devi...

Hello This is my first mail for this list, so please be considerately. I'm trying to build a tiny version of samba for an embedded device. currently im using the version 2.2 with a footprint of smbd 2.4M. Thats to much. Is there a way/patch to build smbd without everything beside file exchage? I don't need printer, swat, ldap,.... support. Just exchange. I have disabled most of the features via .configure but thats not enough. I found a patch for 2.0 which disable some parts of p...

...nt to JIT code and never interpret it, but it looks like I currently have to pay a codesize penalty for the interpreter anyway. Right now this is personal experimentation, but if Mozilla decides to use te LLVM JIT for some of our Mozilla2 projects we'll definitely be contributing to reduce the footprint as much as possible, as well as the MSVC thiscall support I mentioned before. - --BDS - -- Benjamin Smedberg Platform Guru Mozilla Corporation benjamin at smedbergs.us http://benjamin.smedbergs.us/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) Comment: Using GnuPG with Mozilla - h...

...mplemented (the structure/interface/features). Let me first explain what I aim for (and how it is currently in my head). First of all, it should be straight-forward to manage a list of systems (or groups of systems) that have similar configurations. A config-file could be something like: /etc/footprint/system/proxy-servers.conf [main] boot options = panic=10 acpi=off dist = rhel4as #modules = e100 profile = proxy-servers [proxy01] ip = 10.0.0.1 netmask = 255.255.255.0 mac address = 00:01:02:03:004:05 ... (or even more simple, only hold 1 system) There would be a collection of profil...

...TxD, they kill processes that are hogging resources (quite understandably). Unfortunately for me, my Ruby fcgi processes load up rather ... large (just under 50mb). It doesn''t take much to push it to 50mb, at which point it gets killed. Does anyone have any suggestions for reducing the footprint of my app? I know that there is a profiler script available for benchmarking and such, but it seems that it focuses more on speed performance than memory (correct me if I am mistaken, but all the stats I see are for response time). My app seems rather responsive anyway (both as a qualitative obse...

Which Rails servers are good for a small number (2-5) of concurrent users? A small memory footprint is very desireable. TIA, Jeffrey
