Yes, it is server-based. There is however an
option to adjust the required bandwidth (upper left corner menu, the default is
'broadband' which may be too much for your location). The minimum bandwidth
required is about the same as for Internet radio. So if you can listen to
international radio stations over the Internet without hiccups and buffering
phases in streaming mode, it should work fine in minimal bandwidth mode, but
with connectivity below that, you may indeed have a problem. For normal users,
response time should be more than adequate. It has been in use for years at
PubChem without significant complaints.
Wolf, i would think that the
issue is latency rather than bandwidth. A 10Mb link can have latencies in the
hundreds of milliseconds - movies would play just fine but server-based applets
can still be a pain. Just my 2 cents...

Fortunately such constraints become less and less of a
problem even in remote locations. The same is true for the use of antique
browsers such as your IE6 - which btw is still an officially supported system,
with special consideration regarding image encoding, etc, - but only if your
bandwidth is not exceeded. IE6 reacts nastily if image display requests queue
up..The minimum IE version required by this software is actually IE4, which has
really limited JS capabilities, and cannot even display PNG images.
I selected the
button "single bond" and clicked on the draw area,then it cost several seconds
to generate bond on the screen. I guess it may fetch something from the
server instead of generating them by the client itself. Also, it made my
IE explore crashed two times!!
I have to say
"ChemWriter" is much better, since it is fast and work well even on the IE6
explore.
Sorry for my terrible
english.

Strangely, this review is completely
missing the technologically unique Web sketcher originally developed for PubChem
and accessible in an enhanced version at www.xemistry.com/edit/frame.html
This tool is the
only full-featured Web structure editor which is *not* a plug-in (with all its
platform and installation issues) nor a Java applet (with its own JVM engine
presence and versioning problems, plus download time issues). Compared to other
Web editors of any kind, it can access a much broader range of Internet
structure databases directly (over 2 dozen currently), and it supports a much
larger list of I/O formats (for example, it supports SDF3000 and original
ChemDraw CDX/CDXML or ISISDraw skc/tgf files as well as direct input and
decoding of SMILES, SLN, JME strings, PubChem CIDs, cas numbers, compound names,
etc.).
