Design Notes

These are points arising from discussions, etc. Note most of the design goes straight into the web in place, not here. This is mostly historical.

Performance of FIND server 29 May 91

Conditions: Loops over XFIND COPY TAPE CMS with SHOW DATE. Normally loaded machines (around 14:00) running VMS and accessing CRNVMC with HTTP/TCP/IP. Loops/min Loops/sec One process on one machine at a time: VXCRNA 27 .45 Hz ONLINE 27 .45 Hz One process on each machine, all at the same time: VXCRNA 25 .4 Hz ONLINE 20 VSOC28 18 VSOC06 16 Total 79 1.3 Hz Thee spawned processes each machine, all the same time (12 in all): VXCRNA 49 .4 Hz ONLINE 21 VSOC28 20 VSOC06 19 Total 109 1.8 Hz The last test apparently brought the VM TCP interface close to running out of buffers and losing telnet connections. This is with a version of the daemon which incorrectly gives precedence to incoming new connections over messages on existing connections, and so the number of connections at any one time may have been larger than necessary. The test demonstrates that the server (if not the IBM) behaves well under overload. The throughput figure is sufficient for our estimates of peak load on a running system.

From Feb 29 meeting:

See browser outline module dependency diagram we discussed. I have since come across many ways in which to have a tree in there would be useful: for example, putting in hidden text, comments, and things which we don't know how it interpret but we want to keep in the file.

After meeting with Huettenberger from NeXT:

we should combine the San Antonio meeting ith a visit to NeXT.

Hot spots: if they are permanently visible, then that uses up a character style, such as underlining, bodfacing etc. Whichever style is used, this will at some point conflict with a style that already was used in the document by its original author. Therefore:

What are the conditions for releasing W3 to academic NeXT users?

Meeting with L. Simoni (Bologna)

do we have a server for VAX help libraries? how difficult is this?
