maximising network file transfer speed

on a 1Gbps LAN, the theoretical transfer speed is 1024/8=128MB/s. but my experience of copying files between PCs and/or NAS through LAN is in the range of Kb/s or a few MB/s, an extremely far cry from the theoretical speed. my guess is that the limitation is in the software or OS. did a quick search on how to improve network transfer speed, many “solutions” out there, but the tip from howtosolutions.net appears to effect some improvement in speed:

1. Disable LSO (Large Send Offload) found in Advanced settings of network card in Windows Device Manager.

2. Enable and maximise the value of “Jumbo Packet” in Advanced settings (this is found in the comments within the above post)

works on physical LAN. not sure if it works for WiFi connections though.

SG50 heart-shaped logo

was looking around for a SG50 heart-shaped logo, but only found the red circle, and the heart map. so decided to ‘combine’ the two, and here you go, my little ‘creation/contribution’ for/to our celebration (:

after 10 years …

… of “无官一身轻”, i am now an RO again! to only 1 colleague (: any difference 10 yrs before, and 10 yrs later? i would think so. i would treat my “reportee” as a co-learner more than ever before. i hope i would learn and grow as much as she would learn and grow in the time that we work together, and with/from the pple that we will be working with.

thoughts on post-workshop reflection

yes, we’ve completed our first round of ICT for SDL and CoL Clinic for primary school teachers (TRAISI code: 12541, or 12541-00001). was reading wj’s facilitator reflection, and it just occurred to me that we have missed an excellent teachable moment!

“我比较不解的是-其实他们之间分享了很多实例了,老师要的是什么实例?……”

some teachers have indeed voiced during the first f2f, that they would like to learn and see 实例。 yes, in the 1-month online discourse, many tried-n-tested examples have indeed been surfaced by fellow course participants. so what are they exactly looking for? wj’s hypothesis is they may be looking for technical hands-on (knowledge). my guess is it stems from their less sophisticated epistemic beliefs. some do not see that ‘learning’ has occurred if ‘learning’ does not take place the way s/he may have 预期ed.

as the self-proclaimed mentor to wj, her performance is a reflection of my hand-holding. there’s much to learn cos i am just more experienced by 2 workshops *hahaha* *oops*. there’s quite a number of things to take note, many of which i have previously noted down. after reading wj’s reflection, one key takeaway for me is the key influence of the facilitator’s paradigm. not mine, but that of whoever i am hand-holding. the “struggle” could be a great one, for s/he will need to manage two sets of paradigm shifts — participants, and oneself.

that’s all for now. perhaps “more later” (Wu, 2010, 2011, 2012, 2013, 2014, 2015) (:
