Hi,

I'd run into this topic some time ago and there are some resources I think
you may be interested in. However I have no concrete answer.

Hi,

Anyone ever think about the performance of ctags ?
Parsing thousands of files could be really slow , and if a time stamp
checked before parsing files ( avoiding files that has totally no change at
all ) , it should be much faster.

Right , just ideas , haven't tried before , and .. don't know how to implement
for the while .. bit complex somehow.

Could anyone help me check this ?

Hi, Reid,

Just back to my box , tried with Chromium Browser , seems like i shouldn't
worry about this.
