Inconsistent and long load times, posted by Fabian on Fri Nov 15 10:59:51 2013
|
We recently installed ELOG and it works pretty well, but the load times are rather inconsistent. Most of the time
it is very fast, but it also often hangs for around 5-10 seconds while loading. It seems to affect all parts of
the page that are returned at random, so sometimes the main html file will hang, sometimes the css file and
sometimes the images.
The hardware it is running on is nothing special, an older 3 GHz Celeron, but it should be fast enough. It is
running on Debian 7.
Any ideas what the problem could be, or how I could investigate it further to find the bottleneck? |

I'm not an expert in debugging web applications. Here are my two cent:
We once had a problem when we hosted very large logbooks (several 10 thousands of entries) that the server would run
out of real memory and was slowed down by swapping. Therefore my first idea would be to monitor the server: Is
the CPU load peaking? What happens with the memory consumption? Any other suspicious process running on the server?
But it could be as well a network or browser problem. Did you try different browsers?
Did you check the elogd log file? |

The logbook only has a few hundred entries, elogd is using only around 20-30 MB and there is enough free RAM. The load
average for the server is around 0.2, elogd only uses 5% CPU at most when it is accessed and the CPU is idle most of the
time.
Strangely it happens mostly when using Chrome, and almost never with Firefox. I captured the network traffic, but I can't
see anything unusual. It just takes very long until the answer is returned by the elogd server. |

My tuppance worth. I have noticed (firefox) that some attachments take rather longer than might be expected to upload. I
originally thought this was the ghostview program processing say a pdf to make pngs etc, but have more recently started to
question that assumption. No solution or much clue, just another observation. |

Hi,
we have a problem. After windows updates, the elog service doesn´t start:


What can we do?
Best regards,

After I uninstalled the software and reinstalled, the function is working again.
Thanks.
