Firefox中的农业网格性能问题

Question

我们正在使用农业网格版本'17 .1.0'。

我们已经观察到指标，在Firefox中渲染网格所花的时间比chrome所花的时间要多。

捕获的日志：

Chrome浏览器：“ BalancedColumnTreeBuilder：2064ms”

Firefox：'BalancedColumnTreeBuilder：10766ms'

  BalancedColumnTreeBuilder.prototype.createBalancedColumnGroups = function (abstractColDefs, primaryColumns) {
    console.time('BalancedColumnTreeBuilder');
    // column key creator dishes out unique column id's in a deterministic way,
    // so if we have two grids (that cold be master/slave) with same column definitions,
    // then this ensures the two grids use identical id's.
    var columnKeyCreator = new columnKeyCreator_1.ColumnKeyCreator();
    // create am unbalanced tree that maps the provided definitions
    var unbalancedTree = this.recursivelyCreateColumns(abstractColDefs, 0, columnKeyCreator, primaryColumns);
    var treeDept = this.findMaxDept(unbalancedTree, 0);
    this.logger.log('Number of levels for grouped columns is ' + treeDept);
    var balancedTree = this.balanceColumnTree(unbalancedTree, 0, treeDept, columnKeyCreator);
    this.columnUtils.depthFirstOriginalTreeSearch(balancedTree, function (child) {
        if (child instanceof originalColumnGroup_1.OriginalColumnGroup) {
            child.setupExpandable();
        }
    });
    console.timeEnd('BalancedColumnTreeBuilder');
    return {
        balancedTree: balancedTree,
        treeDept: treeDept
    };
};

chrome和firefox的BalancedColumnTreeBuilder代码执行时间之间存在巨大差异。
