...has a high percentage of overhead for tcp. Add to that the replica check to ensure you're not getting stale data and you have another round trip for each file. Your 123k directory entries require several frames of getdirent and over 492k frames for the individual fstat calls. That's roughly 16us per frame. Can you eliminate the fstat calls? If you only get the directory listing that should be significantly better. To prove this, do "echo *". You will instantly see your 123k entries.

...pection has been done. Some benchmarks comparing the filter-based resampler at Q3 with the FFT resampler with overlap = in_len / 2, using 20ms chunks of data. (-O3 -ffast-math, FFTW3, gcc 4.3.0 on x86_64) 16=>48: 59us vs 19us 16=>44.1: 204us vs 34us 16=>8: 13us vs 7us 48=>8: 32us vs 16us This is actually much faster than I expected. With -O3, the overhead of copying, applying window etc is 20%. With all options, the overhead sinks to 10%. I've done listening tests when converting wb_male.wav to 44.1, 48 and 8khz, and there aren't any obvious artifacts. I also did a 16=...

Hi, I have a situation where an apache web server is trying to locate the IndexDocument for a directory on a gluster volume. This URL is being hit roughly 20 times per second. There is only 1 file in this directory. However, the parent directory does have a large number of items (+123,000 files and dirs) and we are performing operations to move these files into 2 levels of

Greetings, I am resending this as it doesn't appear in the archives and no one responded...maybe it got routed to /dev/null or something :-) I have asked this question the Scientific Linux mailing list (a few months ago) and got the suggestion I talk to the kernel guys. I pinged a kernel guy I know, and his suggestion was to ask the Nouveau list. So here I am. :-) I have had my work laptop

Hello, A user (cc'd) reported that nouveau's enabling of MSI causes the card to not work on his setup [1]. I think the situation is that MSI is just not supported by the underlying motherboard, even though the card, and probably bridge, support it just fine. It's a very old board. The nouveau code does: pmc->use_msi = pci_enable_msi(device->pdev) == 0; Does it need to do more
