Mostly out of curiosity: I've seen people advising that we set SO_{RCV,SND}BUF to 8192 as an optimization. I added a call to getsockopt() to grab the old (default) value before setting it to the new, and it turns out (on DG/UX), that the default value is 8760 (or 8704, when you throw in the fact that packets are travelling between different sublans), so the 8192 "optimization" is a

Hi. Between 2 linux (2.6.11 client and 2.6.14 server) machines connected by a 100Mb link I get samba performance copying a file from the client to the server through a smbmounted share of around 4.2MB/s Is this to be expected? Or can it be improved (and if so, how?) I've tried tweaking SO_(SND/RCV)BUF (after reading numerous articles on samba performance...), but it doesn't seem to have

R 3.5.1 is installed under Linux Mint 19 from binaries r-base and r-base-dev from ubuntu bionic-cran35.? Mysteriously, packages using libRblas cannot be compiled.? I get: libRblas.so: cannot open shared object file: No such file or directory.? And indeed, I find no libRblas.so. Any ideas about how to fix this? Thanks, Steve

Hi All, Been having problem using the AMI, i've got this PHP script: $socket = fsockopen("1.2.3.4","5038", $errno, $errstr, $timeout); fputs($socket, "Action: Login\r\n"); fputs($socket, "UserName: amiadmin\r\n"); fputs($socket, "Secret: amiadminpassword\r\n\r\n"); fputs($socket, "Action: Command\r\n"); fputs($socket,

Hi, Apologies this is a bit lengthy. TLDR: I'm using Dragonegg + LLVM 3.2 and uClibc, and am finding that using the Fast register allocator (i.e. -optimize-regalloc=0) causes miscompilation of setsockopt calls (5-arg system calls). The problem doesn't happen with the default register allocation path selected. It can be worked around by manually simplifying the system call setup
