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 subdirs. We are seeing very slow response times (around 8 seconds) in apache and also when trying to ls on this dir. Before we started the migrations to move files on the large parent dir into 2 sub levels,...

...directory entry. That's a lot of tiny network round trips with fops that don't even fill a standard frame thus each frame 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 wil...

Hi R users, I am trying to assign ages to age classes for a large data set (123,000 records), and using a for-loop was too slow, so I wrote a function and used apply. However, the function does not properly assign the first two classes (the rest are fine). It appears that when age is one digit, it does not get assigned properly. I tried to provide a small-scale work-up (a...

...eries per day, it makes sense to order your rules to accept the DNS queries first, followed by http traffic, and to accept the smtp traffic last. This ordering would cause 111,000 packets to be evaluated by the first rule, 11,000 by the second rule and 1,000 by the third rule giving a total of 123,000 times a packet was inspected by a rule. If we reversed the order we would see 111,000 for our first rule, 110,000 for our second rule and 100,000 for our third rule, giving a total of 321,000 examinations which is 2.6 times more than our first example. Don't forget it's only the ini...
