    <p>I'm working on a multiplayer game. The principle is simple, each of the two players sends each other periodically 512 bytes every 50 milliseconds.</p> <p>The problem is that about every 20-30 seconds players stop receiving data for sometimes one but sometimes even up to 20 seconds (though, sending had not been interrupted).</p> <p>At first I thought that this is caused by a slow network connection on either my side or on the side of my remote PC which I use for debugging.</p> <p>But then I noticed that all network traffic on my side slows down at the same times when the game stops receiving data.</p> <p>So I started <code>ping &lt;my-local-router&gt;</code> and this is what it shows me:</p> <pre> When the game isn't running: ... 64 bytes from 192.168.1.1: icmp_req=4520 ttl=64 time=4.89 ms 64 bytes from 192.168.1.1: icmp_req=4521 ttl=64 time=7.96 ms 64 bytes from 192.168.1.1: icmp_req=4522 ttl=64 time=10.5 ms 64 bytes from 192.168.1.1: icmp_req=4523 ttl=64 time=7.21 ms 64 bytes from 192.168.1.1: icmp_req=4524 ttl=64 time=8.10 ms 64 bytes from 192.168.1.1: icmp_req=4525 ttl=64 time=3.37 ms 64 bytes from 192.168.1.1: icmp_req=4526 ttl=64 time=5.12 ms 64 bytes from 192.168.1.1: icmp_req=4527 ttl=64 time=3.29 ms ... </pre> <pre> When the game is running: ... 64 bytes from 192.168.1.1: icmp_req=47 ttl=64 time=6.99 ms 64 bytes from 192.168.1.1: icmp_req=48 ttl=64 time=1.69 ms 64 bytes from 192.168.1.1: icmp_req=49 ttl=64 time=2.60 ms 64 bytes from 192.168.1.1: icmp_req=50 ttl=64 time=2.88 ms 64 bytes from 192.168.1.1: icmp_req=52 ttl=64 time=9210 ms 64 bytes from 192.168.1.1: icmp_req=53 ttl=64 time=17144 ms 64 bytes from 192.168.1.1: icmp_req=54 ttl=64 time=16214 ms 64 bytes from 192.168.1.1: icmp_req=55 ttl=64 time=15372 ms 64 bytes from 192.168.1.1: icmp_req=56 ttl=64 time=14482 ms 64 bytes from 192.168.1.1: icmp_req=57 ttl=64 time=13486 ms 64 bytes from 192.168.1.1: icmp_req=58 ttl=64 time=12511 ms 64 bytes from 192.168.1.1: icmp_req=59 ttl=64 time=11546 ms 64 bytes from 192.168.1.1: icmp_req=60 ttl=64 time=10591 ms 64 bytes from 192.168.1.1: icmp_req=61 ttl=64 time=9626 ms 64 bytes from 192.168.1.1: icmp_req=62 ttl=64 time=1.34 ms 64 bytes from 192.168.1.1: icmp_req=63 ttl=64 time=3.33 ms ... </pre> <p>It seems that the game is causing the router to become unresponsive.</p> <p>I don't have any P2P running on my local PC, but that doesn't even sound relevant since I don't experience the slowback when the game isn't running.</p> <p>I'm new to UDP programming and I'm getting clueless with this, especially since the 512 bytes every 50ms seems like quite a small bandwidth to me (when I do run P2P, it easily runs 1.5MB/s).</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
