I checked all the documentation of couch DB. There is no mention of the system requirements.
I want to install CouchDB on AWS nano machine and wondering if it is possible.
Question
What are the CoupchDB minimum system requirements? (RAM, CPU, disk)
I have not seen any official minimum requirements. I have the smallest DigitalOcean droplet running Ubuntu Server with the CouchDB 2.1.1 on it (and it previously ran version 1.6.1). It works well, but is only used as a test machine for a development project. The spec is one CPU, 512mb RAM and 20gb SSD disk.
We run CouchDB in production on AWS using Docker. In general, we have found that we need at least a t2.medium for each node to keep up with the CPU and memory demands, i.e. each t2.medium instance has 2 CPU cores and 4GB memory.
We are planning on releasing a more in-depth analysis shortly.

For our project, we are setting up MarkLogic cluster on Azure.
Is there any major performance difference when it comes to Windows or Linux ?
It would be great if there are any reference links for the same
I have done installation and configuration on both, in real terms it does not matter while setting up.
So want to know from performance perspective, does it really matters?
Workload
Current size >15M XML files which needs to be loaded into MarkLogic
Weekly 18K xml files will be ingested
In general, no. There are some minor performance differences, but it depends on your specific workload. For those edge cases, my understanding is that Linux will typically edge out Windows. But focusing on application design best practices and query optimization is significantly more important than the host OS.

i am newbie in network administrator..
One week ago, my server work perfectly. My Server can serves 600++ users at the same time and only use 40% cpu.
Today there is something wrong with my server. My server shows 100% cpu usage when it serves 100 users at the same time.
After i check, i found a process /boot/.IpTables that use high cpu.
What happen with my server? Is my server hacked or what?
This is SS my server process :
OK, looks like your system has been had. I did some googling for /boot/.Iptables, and it appears to be malware.

My personal recommendation would be to take the machine of the network immediately, clone the drive to a USB disk, and re-install (preferably w/ a new set of passwords, and all available patches applied).

i would like to use my older Samsung netbook for some coding (php, apache, mysql).
But Ubuntu distribution is quite slow.
Can somebody recommend to me some ultra fast and efficient linux distribution for netbooks?
Thanks and regards.
Take a look into this link here
Although I would recommend you either of the following 2 distros for small memory consumption systems
CentOS minimal ( Just install the xWindow package and you will have a full fledge Centos system with a memory footprint of approximately 300MB)
DSL ( Damn Small Linux) is a well renowned linux distro with a 50 MB memory footprint.
I would personally recommend using CentOS since you can easily find packages of almost anything for CentOS without any issue

Are there any minimum server requirements for using Apache SVN? If not, what are some general server specifications used for Apache SVN? Any information on server capacities for Apache SVN would be appreciated!
As long as your team is not extremely large, a very decent server is enough. Even a virtual server with about 1 virtual CPU and 1GB RAM running on a decent real CPU is enough. I'd say it doesn't need to be any faster than a server you'd use as a file server.
I'm using it myself on a very limited v-server and it works very well.
I have yet to find an Apache httpd configured Subversion server that's underpowered. Subversion itself doesn't take up a lot of bandwidth. I would still suggest that the server be dedicated. It isn't that Subversion sucks up a lot of power. More likely, whatever else you do will suck up too much power, and it will slow down Subversion. I was at one site that kept on piling more stuff onto the Subversion server (including database services) and then ware upset that Subversion was slow. Everything on that machine was slow.
The main concern would be bandwidth which seems to matter much more than the server itself. Also, be careful with NFS mounted disks (although Netapps seem fine).
I found this http://subversion.apache.org/faq.html#server-requirements but it's probably not enough detail.

When i try to offline a disk in a zfs raidz pool (the raidz pool is not mirrored), zfs says that the disk cannot be taken offline because it has no valid mirror.
Isn't one of the properties of raidz that it has a redundant disk (or even 2 disks in raidz2)...?
Could you give a bit more about your configuration please? What are the commands you are using? If I'm understanding your question that should work.
Note that:
You cannot take a pool offline to the point where it becomes faulted. For example, you cannot take offline two devices out of a RAID-Z configuration, nor can you take offline a top-level virtual device.
