Evaluation
Evaluation of the Workshop was done in the form of an evaluation questionnaire completed at the end of the workshop. 16 forms out of 19 were returned to TERENA, who collected the results summarised below.
6) The most useful sessions were, in the order:
7) The most useless were, in the order:
8) Were there any topics that you think the workshop could have covered, which were not covered?
I`d like more details on HTTP/1.1 protocol, cache directives and protocols (WCCP, NECP).
Authentication problems in transparent caching and possible solutions.
Proxy autoconfiguration issues.
[session N.] 8
[session N.] 8
No.
There are any way to transparent proxy ftp sessions. (not netscape, …) ** think *** *** *** . Why, why not?
Web cache administration cost -setup time, keeping a production installation
A relation of caching servers to network equipment (load balancing, etc.)
Real-world scenarios.
The little details that we could do to fine tune the caches (how many disks, how much we should fill them with objects, etc.)
Content filtering.
The facilities and organisation got the following scores:
The participants answers about this set of open question were very different in nature. Some words in a few sentences were particularly difficult to understand, in those cases a number of stars "***" is used to indicate the editors inability to decode the handwriting.
13) What I liked most about the whole workshop:
Both workshop contents and the possibility to exchange ideas with other people!
The exchange of ideas and results between different managers.
The opportunity to meet people and hear about evolutions in www caching.
Easy way of getting contact with participants or speakers (small group of workshop members)
The professional level of most of the presentations
If someone doesn`t heard about anything before the WS, he could *** the basics (but not ** order ? e.g. we heard about installing SQUID before we ***, ** to organise servers)
Exchanging knowledge.
High technical standard of the classroom. Practical exercises were prepared very well.
*** *** good overview
S.1.4
Reference to SQUID, cache architecture, future of caching technology.
To meet people who are deeply involved in the topics that were covered.
14) What I liked least about the whole workshop:
Practical sessions.
The cofee :-)
Some boring noise in the workshop room.
Practical session too short: free time
There were no information on what is covered by TERENA and what should be paid by participants. Many slides were missing from the workbook.
We didn`t know before the workshop things punctually. E.g.: I didn`t know: we have to organise ourself the lunch or we get (but fortunately we got :-))
Not enough time to configure SQID/MRTG with SNMP properly.
There was too warm in the room
No tea a place ;-)
Some of the hands-on (like compiling stuff for Linux that everyone knows it will not fail!)
Little more things about the performance issues.
15) How could we have improved this workshop for you:
It was very good!
Download much of the files necessary to the practical session before and also compile them. Let us just the configuration.
Better pre-conference information, more up-to-date workbook.
More "documented": also the sessions, & also the event (e.g. ***)
Having more commercial products
Examine-reference real-world scenarios, problems encountered, things to avoid/look for.
I will use them when configuring my cache in the future.
16) Did the workshop met your expectations,
There were 15 responses: 15 yes
17) Do you plan to use any of the information you have been given at this workshop?
Yes. To organise a seminar for cache (& system/network) administrator in our organisation.
- To evaluate my installation of caches.
- To improve the statistics of my caches.
- To make a real evaluation of cost/benefit.
Yes.
1. Upgrade to new version of SQUID.
2. Configure SQUID with new options suitable for my environment.
3. Use MRTG to get ** of *** SQUID, with SNMP
Info from 6 session.
SQUID, Cache system architecture.
Better quality reports about caches to the management. A couple of ideas will be tried, tested in our environment.
Yes. I want to setup MRTG to tack my caches.
Not directly. Currently SQUID isn`t an option for our 1st level web cache system.
I am going to use it to make decisions about starting cache servers in small institutions.
Yes. Nearly all.
Yes, definitely yes.
Yes!
18) Further comments and suggestions
Don`t use dark slide, in order to allow the "user" to write on them.
Please put all showed slides into a downloadable ***. Then I can view again all working example, and I think then I can try out those things are easily
For real practical work, much *** would needed. However, *** *** that practical exercises really needed.
